Royal Palace of Caserta, Paestum, Naples

The Royal Palace of Caserta (8:30-7:30, free for the first Sunday of a month) is a former royal residence in Caserta, southern Italy, constructed by the House of Bourbon-Two Sicilies as their main residence as kings of Naples.
Located 35 km north of the historic center of Naples, Italy, the complex is the largest palace erected in Europe during the 18th century. In 1997, the palace was designated a UNESCO World Heritage Site; its nomination described it as "the swan song of the spectacular art of the Baroque, from which it adopted all the features needed to create the illusions of multidirectional space".
The Royal Palace of Caserta is the largest former royal residence in the world, over 2 million m3 in volume and covering an area of 47,000 m2 and a floorspace of 138,000 square meters is distributed in the five stories of the building.
Paestum was a major ancient Greek city on the coast of the Tyrrhenian Sea, in Magna Graecia. The ruins of Paestum are famous for their three ancient Greek temples in the Doric order dating from about 550 to 450 BC that are in an excellent state of preservation. The city walls and amphitheatre are largely intact, and the bottom of the walls of many other structures remain, as well as paved roads. The site is open to the public, and there is a modern national museum within it, which also contains the finds from the associated Greek site of Foce del Sele.
Paestum was established around 600 BC by settlers from Sybaris, a Greek colony in southern Italy, under the name of Poseidonia. The city thrived as a Greek settlement for about two centuries, witnessing the development of democracy. In 400 BC, the Lucanians seized the city. Romans took over in 273 BC, renaming it Paestum and establishing a Latin colony. Later, its decline ensued from shifts in trade routes and the onset of flooding and marsh formation. As Pesto or Paestum, the town became a bishopric (now only titular), but it was abandoned in the Early Middle Ages, and left undisturbed and largely forgotten until the eighteenth century.
