#yakhchal #yazd #windcatcher
How did the ancient inhabitants of the hot Iranian desert keep themselves cool during the intensely hot summers where even being in the shade is very unpleasant?
Well, besides the windcatchers they had in their homes of course, since we spoke about them a while ago.
Think about being in the middle of a hot dry desert, it would be a blessing to be able to drink cold beverages and eat ice cream in the middle of summer to cool off, or to keep your meat, dairy, fruits and other foods fresh for longer periods of time by cooling them.
But I am hearing you asking yourselves.. ice?? how on earth would they be able to provide ice in the middle of a hot and dry desert?
The answer to that is simple yet innovative; build a Yakhchal.
We don’t know for certain where the first ice houses were built on the planet, and we aren’t sure about when the first yakhchal was built either but we do know that around 400 BCE the Persian engineers were already mastering the art of storing ice in the middle of the desert, it was already a widespread phenomenon around this time.
This shows that the actual invention of the Yakhchal happened much earlier as you don’t master something by doing it for a short amount of time, but it’s unfortunately unclear for how long.
The practice of storing ice itself was already long established by the time of 400 BCE, we know for a fact that the Mongols were already storing ice for quite some time, although again it’s unclear for how long, but there are accounts of them doing it before 400 BCE.
Ice was mentioned in older texts in Iran from before 400 BCE, but there was no mention of how it was produced, which doesn’t allow scholars to interpret that as yakhchals already being used for very long before 400 BCE, although it is of course hypothesized as I said earlier, you don’t master something by doing it for a short amount of time.

Amazing how inventive ancient people were. They often achieved a lot with very little. Todays everybody talks about sustainibilty. Everybody wants to save energy and to produce less waste. But if we want to get there we need to rediscover these forgotten masterpieces.

You have made an absolutely valid point
if ancient people werent so inventive you would not be sitting here with 6 billion fellow humans
I was in Iran in the 1990's and visited an isolated desert village. It didn't have a yakhchal but it's water was supplied by snowmelt channeled from the mountains via a qanat. A large adobe building built above where the qanat was exposed at the surface provided a cool place for residents to take a break from the desert heat. It was several degrees cooler than the outside air.
I'm from Iran and I've seen the structure of yakhchals used in many "Zoorkhaneh"s(ancient gym). This kind of structure helped ancient body builders not to sweat.
That kind of ancient gyms go back to more than 1000 years ago. They also had one or a few musicians called "Morshed" who perfomed music during exercises and sometimes gave them peptalks and words of wisdom which is amazing. In addition to body building, they also practiced wrestling.
that is surprising, I would have thought life was physically demanding enough to surive without intentionally doing more work than needed.

probably for upper class who don't move their As*es 😅😅
Iranian old-style wrestling might not be popular nowadays but it did influence bodybuilding & wrestling (pehlwani & kushti) across South Asia. It's fascinating how ancient Persians invented air-conditioning for their gymnasiums, and cheering music in the background (more like upperground) too
Persians and Armenians have been neighbors fur over 2500 years. As an Armenian I am honored to have neighbors like Iran. Our cultures survived extinction and must go on.
Definitely must go on
As someone who works on air conditioning and refrigeration, these ancient techniques always fascinate me. Thanks for another great video.
Thank you 🤗
I also studied hvac and am amazed at how they did this without refrigerants
They had cooling systems in Chicago that used ice cold lake Michigan water back in the late 1800s.
I also read about some worlds fair type thing out in Tempe, Arizona back in the 1980s that had giant wind catcher type cooling towers that could passively lower the air temperature by 10 or 20 degrees over a large area of the event pavillion. I think some stadiums and arenas built in the 1990s use similar principles.
@@PhilLesh69 very cool, pun intended
@@HistoryWithKayleigh do you know the Giza pyramid is also a refrigeration? It's a exact replica of a jet steam refrigeration. There's a one hour video here detailing it
as a person who lived long enough to remember going to an ice factory to buy big blocks of ice, the cost of having a centralized ice source and having to commute to and from, would be prohibitive compared to just having ur own freezers. water and power are really cheap, compared to teh cost of having to move to and from an ice house
The wood ash is alkaline and the lime is acidic. When you mix wood ash into stucco/clay, it instantly becomes very sticky as if you'd used Portland cement. The protein in the egg yolk is a binding agent.
In Caspian sea shores where I was born and raised, there are severe cold winters with lots of snoe turning into ice. In those regiones there were no ice houses like in desert areas but there were other methods (simple ice pits covered with insulating materielas built in small scale and locally all over the place) to have ice in summer.
Back when I was a kid in the 1950's growing up in Central Ontario, Canada, a Local Saw Mill, cut ice off of the frozen lake in the Winter, and stored it in long sheds, in blocks, covered in sawdust. They would go around in the summer with wagons, the ice covered in sawdust and tarps, and the men would chip off chunks for the ice boxes in the village. Don't know how long they had been doing this, as I was born in 1948. It was in the 60's when they closed down, that electric freezers came to the area. Lot of things changed in the 60's. But that was the cost of progress :)
We did the c same in California, Lake Tahoe…
David Cadman
This was a common practice in both Europe and North America.
Cool🤫
In my country, we're still using similar technique until these day.
We use rice hull to cover ice.
We can store ice in rice hull without melting it down for very long time and without electricity.
Electricity is a bit expensive here and not everyone can use electricity.
I remember an ice house next to the RR Station. The ice was stored in saw dust and the ice man delivered ice for the ice boxes in homes. The ice was replaced from the train. This was on the Alberta praires during the 1940-50s when I was a kid. That has all disappeared and the tracks were ripped out about 20 years ago.
This is incredible. As an lover of physics this is incredible knowledgeable and as a survivalist this is definitely going in my book. Bless!
Thank you🤗
We have Volcanic Ice Caves in New Mexico with ice year round even at 100°Farenheit
Great job Kayleigh
Thank you Brien! 🤗
@@HistoryWithKayleigh My pleasure
@@brienfoerster Mr Foerster has always been a favorite of mine. When Brien speaks, he means what he says, no sugar coating. So if Brien liked the video that’s like 3 thumbs up.
@@jeffhenderson934 Many thanks Jeff.
@@brienfoerster Have always enjoyed your work and insights Brien. I have a better understanding and appreciation of the ancient past thanks to those like you and Kayleigh. Continued success for you and my deepest thanks for all the knowledge. I promise, I will be taking one of your South American tours. It’s been a dream of mine since the 8th grade. (Unbelievable teacher that spent a month on the Aztecs, Maya and Inca. And then handed me her copy of Chariots of the Gods)
another fascinating video Kayleigh , ice in the desert sounds unbelievable , these ancient people were obviously much smarter than we give them credit for . thanks for the upload .
What Kev said 👆
They sure were 🤗
It's a form of chauvinism to presume that we are the peak of a constantly rising curve of technological advancement.
Most of our understanding of Egypt and the pyramids is based on the interpretations made by people who stumbled upon massive ancient buildings, looked around, and couldn't find any construction equipment and therefore concluded that they must have lifted all those stones basically by hand.
Lost ancient technology is a very interesting subject. There is more that we do not know about Earth's early civilizations than we know. The more we rediscover, the more questions arise.
Agreed 🤗
With every discovery an answer and two more questions. The mystery of the past is slowly being understood.
I live in the UK. We have had ice houses here since the 17th century. We would break ice off lakes in winter to store stuff all year round in underground stores. Enjoy your Malibu K, peace to ya.
Thank you🤗 ice houses are really cool 😉
Probably much longer than that. Be safe Darren.
You have to get down a certain depth in the ground,depending what part of the world you're in and you're basically escaping what the temperature is on the surface. Where I live in the southeastern US it doesn't get as hot as Persia (normally anyway lol) at least not on average and we're far enough north we could actually have a lengthy winter. But,we have a high water table,when we've had wet weather I've seen water hit at 4ft,so a lot goes into how deep it would need to be if possible at all. The desert might be the best place to do it because of the dryness itself.
I think your right. The moisture we have is a heat transfer so the dry air might keep a more stable temperature.
evaporation of water into dry air causes a considerable temperature drop. Not so in humid air. I think that's why this works. In the Southwest we have swamp coolers which are basically fans blowing on wet pads and they cool the air far cheaper and better than an air conditioner when it's dry out.
We really should incorporate more of these ancient techniques in modern buildings! This would make for a great refridgerator anywhere in the world (Basically a large rootcellar with a domed roof). Even if you don't use it to store ice, it'd still be great to cut down on the electricity use these days!
Love how they actually used water on the south side, to help cool the surrounding air!
They were so smart 🥰
They used to transport large blocks of ice from the Rockies by train to be used in large ice houses, ice caves and similar storage methods in cities and towns across the midwest. Many of the older buildings in Chicago still use water from lake Michigan to cool their buildings. Massive pipes run out to deeper colder parts of the lake pull in ice cold water that they dump over massive cooling towers and big giant air movers.
I always prefer taking the basement room when renting a house with roommates, since it stays cool in the summer and I don't mind putting on more clothes in the winter. Where I live, I won't even turn my computer on in the summer until sundown - unless I have a basement room. Home manufacturers here don't think we need AC. Fortunately there's some stigma about living in a basement so no one else ever wants the room lol
@@PhilLesh69 Toronto has a system called "deep water cooling system" that was built 20 years ago that takes water form the middle of lake Ontario and filters it to be used as drinking water. Before it is sent out to the city as drinking water it goes though a heat exchanger to cool a cooling loop that is used for cooling many of the large buildings in downtown Toronto.
I feel like that's a lot of the power of this channel, showing how you can do heating/cooling simply with the shape of a house, instead of adding electric devices. We should be doing that.
I'm already a huge Yazd fan.
That video totally rocked it Kayleigh. Their technology was ingenious to be able to produce ice in a dessert climate, amazing!!!
Thank you 🤗
@@HistoryWithKayleigh The cross eyed thing was my favorite part though 🤣
Haha 😂
Best video on Yakhchals I have yet seen. Well presented! Thanks.
I wonder if a modern version could be designed that uses industrial practices like using municipal water and plumbing, enclosed freezing ponds to keep dirt and germs out, and machinery to break up the ice and convey it into the yakchal, and power it with solar. Sort of like a mash up of a hotel or restaurant ice machine and one of these.
It would be great, engineers are looking into it. 🤗
Great video. There's actually a similar method of chilling that was used mostly in Africa, where you nested a small pot inside a larger one, filled the space with sand (preferably), then poured water over the sand to release heat. You then placed the pot in a dark corner of the house (partially buried in the floor, if possible), and covered it with a lid. It won't get down to refrigerator temps, but it will keep foods reasonably fresh for a couple days, at least.
Oh that's a great way to store food and keep them fresh for longer Rin the hot parts of the world🤗
@@HistoryWithKayleigh It is -- Both of these designs are a little like a root cellar; not exactly alike, but they perform the same function. I seem to recall that the Dynastic Egyptians used something similar to the small-pot (it may actually come from them), but I don't know that for certain.
I think they understood evaporative cooling. There are simple chemical reactions that can be used to remove heat or cool things, too.
They could electro plate metals using primitive chemical acid batteries, after all.
Lovely too see and hear you my friend! 🦢
Hey Rox! 🥰

I really enjoy these videos of ancient technolgies, way to go Kayleigh.
Thank you 🤗
The ancients never cease to astound me. Ice and air conditioning in one of the harshest climates in the world.
Loves to the kitties!✌🏻🐱
The kitties say thanks 🤗
Wow I’m always blown away by your information on this channel. I have binge watched hundreds of hours of documentaries and podcasts. I can honestly say I’ve never heard of this invention. Such a relief from the alien theorist. Thanks you Kayleigh. Much love from Canada 🇨🇦 hoping your channel reaches the world. You my my likes and subscriptions. And i can never help but comment.

Absolutely interesting as heck. I hope the bring these ice houses back. Great videos 🙏
Thank you! Let's hope ice houses get a revival in the future 🤗
Hoe de pre en post Arabische wereld wat innovatie en techniek en kwaliteit van architectuur heeft ingeleverd is enorm, kijk eens hoe de steden zich manifesteren en we nog altijd in verwondering kijken naar hoe het vroeger "beter" was. De moderne beschaving moet toch echt de ogen openen en de uitdaging aan gaan om de kwaliteit van het leven en de leefomgeving te verbeteren. Kortom verantwoordelijkheid nemen voor je eigen gezondheid, medemens en vooral de natuur en dieren vrienden.

Thank you 🤗
As always excellent research. The functionality/artistic blend is unique !!!
Thank you! 🤗
always great to hear you sing, Kayleigh! you should do more of these, Please! had no idea there was ice in the desert so long ago. this is going to be good, darlin! see ya soon!
Less than an hour to go 🙂
@@HistoryWithKayleigh well, now i'll have to watch this again☺ some kinda glitch shortly after the start; it stopped and started a few times. don't know how much i missed. oh well, i'll just get to enjoy it even more🤩☺dang wifi, anyway. been raining all morning, probably messing up the signal. was able to watch most of it and was very impressed with how much the ancients were able to achieve🤯 then remembered my time in southern Arizona. it was January and 90+ daytime but well below freezing at nite🥶 so this all makes sense. still, pretty smart to be able to store ice in that climate. another great video, Klee! thanks, me luv😍p.s.(loved the bloopers😂you know, i can cross my eyes like that, too😏)
For me it was a good trick at the bar to make guys leave me alone 😂
@@HistoryWithKayleigh Ha! love that! tho, personally, i wouldn't be deterred by that. you'd have to prove you had no brain🤡
Very kool, ive heard about these but this was the deepest dive. I just got into the HVAC industry in Arizona and it would be incredibly interesting to do some experimental archeology with this or the wind towers!
Yeah i love the designs of both, it was so much fun to research these 🤗
Great job these are so cool how they we’re made how they function and how it was such a necessity!! Thank you dumplin !!!

I’ve tried to steer away from mentioning her good looks till I’m sure she’s over 18 years of age. I think it’s a jailable offense in Georgia to compliment a underage teenager on her looks or stature.(Lots of odd laws in Georgia. Did you know it’s against the law to give a opossum a perm?)
I'm nearly 30, just less than 2 months left

Great video Kayleigh ... the graphics push your videos up to another level ... such a shame that these ice houses have fallen into disuse, hopefully someone can come up with a workable filter system to keep the ice pure ..... Oh & Malibu out of a can, with no ice !?!... really
Haha it came straight from the fridge, Malibu needs to be cold haha
The graphics were amazing!
Oh thank you! I always try to pronounce things right, just that this is on another level 😅😂
We need to save the yakhchals these are very important piece's of history

Complete new stuff to me. Thank you again for educational content.
Always welcome! Love these subjects 🤗
Excellent piece of information. Kudos. Stay safe and healthy.
What a cool episode! Ice houses has been used around the globe. But this was a very efficient way to do it, and all the way back to 400 BCE.
They were masters in construction 🤗
Fascinating. Thank you.

this makes me wonder what an equipment chamber at the bottom of a 400-meter or larger crater-shaped pit would be like. Hmmm, a slight chill is good for the radio equipment that inst cryogenically cooled, so maybe an unexpected benefit.
cool vid. B)
The 400 meter walls would affect the radio waves I believe. Be safe !
We still use the word "یخچال" = "Yakhchal" to refer to a refrigerator.
Also thank you for your efforts to make these great informative videos.
Ice in summer it blew my mind I want to see this Old way of Doing .
That was AMAZING .
I've seen it done small scale with clay pots and an aquarium pump. I had no idea it was done at such scale.
I wish the world to be at peace so that we could all visit and travel each others places.
And break bread together.
Awesome Video! I want to inform you respectfully. You may already know this though. Lime is a calcium-containing inorganic mineral composed primarily of oxides, and hydroxide, usually calcium oxide and/ or calcium hydroxide. If you take limestone and put it in a fire it will oxidize into Lime. If this was a mistake do not worry, I made the same mistake in a professional environment as well. 😅
Indeed a mistake 😅
I was dealing with a loss in the family and wasn't paying enough attention and put in the wrong photo 😅
Though I cannot remember now exactly where I either read it or heard about it, I recall that there was a monarch in Mesopotamia who boasted in one of his proclamations, either on a stela or in a cuneiform tablet, that he possessed an ice house. It was the earliest one of which I had ever heard, and it must have been a primitive predecessor of later, more-advanced versions. At the time, I surmised that he must have had ice brought down from the mountains to the North and Northwest, and, then, stored in some sort of covered, insulated pit.
Great call on the Pear. One of my favorite fruits where my family trees no longer exist due to whatever reason. The last having an electrical transfer station built on and I didn't get grafts/cuttings prior. Neat, wondering if a video regarding refrigeration or cooling using the evaporative cooling devices that I'm not recalling the name offhand... maybe they're just called evaporative cooler. Neat devices and structures!
Seems like this and the ancient air conditioning tech could be used to reduce electricity use, use them in combination with electric ac
Absolutely 🤗 i feel like we can learn a lot from the ancient world 🤗
Incredible. I have no doubt passive solutions such as this will inspire an entire generation of machines that will be deployable in a post-fossil-fueled world where people are more selective about the ways in which energy is harnessed.
Your presentation and knowledge is outstanding👋 very good job with your videos. And best of all your visual presence is captivating😍
Thanks 🙂
Amazing innovation. You taught me something I was previously unaware of. Thank you. My mother always told me: "Don't cross your eyes. They'll get stuck."
Fascinating. I had never heard of these.
I saw your comment on Matt's latest Ancient Architect video, so decided to look at your channel out of curiosity.
I am already subscribed to far too many channels so always resist for as long as possible ( not always successfully) - but you hooked me immediately.
I have never seen history more beautifully presented, and, yes, that's a multipurpose complement.

Happy to hear that 🤗
Fort Louisburg, NS, has wee little Ice House . . .
That's cute 🤗
The point of making sarooj was that it was was waterproof. The melted Ice would not meld into the building and damage the building. Also, ash is a mixture alkali which is known to inhibit mold growth. Mold grows in damp buildings. Listing the ingredients of sarooj is not the same as a recipe. This is a shortcoming to this video.
Brilliant as always
Thanks Dave!
Iran had some amazing ancient tech.

Large agricultural village found under Jerusalem Arab neighborhood, archaeologists discovered an impressive burial estate, an olive press and many jar fragments, ritual baths, a water cistern, rock quarries, and a dovecote, which the dovecote also acted like a wind catcher, all dating to circa 140 BCE.
Damn that's crazy smart. Don't know if I could have ever figured that out
I know i couldn't have 🙂
The word yakhchal is actually means yakh (ice) and chal (pit) . Also yakhchal is also the modern Persian word for a domestic refrigerator.

Starting a video with the host drinking alcohol is a sure fire way of ensuring the piece will never be used in schools.
Some videos of mine are used in schools, others aren't 😂
I am me, sometimes i drink some alcohol other times i don't 🙂
@@HistoryWithKayleigh The simple solution is not to start any video with alcohol being consumed, as this will broaden the appeal and utility of the video. Perceptions and optics matter a tremendous deal, especially when organisations and business are on the look out for new talent and partnerships.
But, I drank more than everyone else at the last ‘normal’ Christmas 2019 party I attended. So, who am I to judge?
Oh i don't always open videos like that, just at times.
I stopped being apologetic to being myself 🙂

Thank you! 🤗
Good stuff Kayleigh 👌🏽👌🏽👌🏽 I wonder if you could build one in a less arid climate? Like southeast USA 🤔🤔🤔 Id build one.
I think humidity plays the biggest part.. if it's too humid it won't work I'm afraid 🙂
History with Kayleigh it’s definitely humid here! I guess I will just have to stick with building a castle 🏰 thank you for the information Kayleigh!
Thanks for info
Very welcome 🤗
Growing up in Michigan, the U.S. state that looks like a mitten, every couple of years a crew digging a new underground line, sewer, water... would find bits of ice left over from the last ice age - 10,000 years? So I would make the wild guess that 5000 years ago there was more of this ice buried in glacial moraines to give people the idea that if you buried ice it would keep.
And Kodak used to keep its film in old salt mines. There would be a cooling unit at the surface. It didn't take much power to keep the tunnels at freezing temperatures. And they didn't visit these tunnels for weeks at a time. Sometimes the cooling unit will have broken down. Didn't matter the tunnels once chilled wouldn't have risen more than a degree or two Fahrenheit.
We, common 21st century citizens, do not even know which one was the first commercial refrigerator that used electricity. LOL!
There was no concept of copyright so if something worked, just worked.
Hahaha
