The Museum of San Marco or Museo Nazionale di San Marco is an art Museum. - Florence Italy - ECTV

Museo Nazionale di San Marco is an art museum housed in the monumental section of the medieval Dominican friary dedicated to St Mark, situated on the present-day Piazza San Marco, in Florence, region of Tuscany, Italy.
The museum, a masterpiece in its own right by the fifteenth-century architect Michelozzo, is a building of first historical importance for the city and contains the most extensive collection in the world of the works of Fra Angelico, who spent several years of his life there as a member of the Dominican community. The works are both paintings on wood and frescoes. The museum also contains other works by artists such as Fra Bartolomeo, Domenico Ghirlandaio, Alesso Baldovinetti, Jacopo Vignali, Bernardino Poccetti and Giovanni Antonio Sogliani.
San Marco is known as the seat of Girolamo Savonarola's discourses during his short spiritual rule in Florence in the late 15th century.
The building
The Museum is situated in the oldest part of the monastery occupying about half the total space. The building has expanded over time, now taking up a whole block, and part of it is still occupied by friars today. The oldest section of the building, built over the medieval Sylvestrian monastery, was constructed by the architect Michelozzo at the specific request of Cosimo il Vecchio de' Medici and his expense, to house the reformed Dominicans of Fiesole, an order at that time led by Antonino Pierozzi. Over about ten years (1436-1446) Michelozzo completed an extremely modern and functional monasterial building project which contributed to the glorification of Medicean patronage. Michelozzo made use of the pre-existent wall structures of the Sylvestrian monastery complex which date back to the end of 13th century. Michelozzo ably linked together the ground floor rooms around a harmoniously-proportionated cloister and raised the levels of these buildings to create the dormitories on the first floor with a large number of cells to suit an expanding monastery.[1]
Sant'Antonino Cloister
The cloister is behind the church and it introduces the visitor to the sight of the splendidly poised architecture of the monastery, a typical example of a measured and orderly Florentine Renaissance architecture. The sight of Saint Dominic Adoring the Crucifixion, painted by Fra Angelico opposite the entrance is uplifting. Originally this was the only painted image decorating the white cloister. The appearance of the cloister was changed during the 17th century, when the monks of San Marco decided to celebrate the figure of St. Antonino by commissioning the most famous Florentine painters of the time to paint a cycle of lunettes depicting Scenes from the life of St. Antonino.
Sacra conversazione by Fra Bartolomeo
The large room, which can be entered from the right side of the cloister, occupies all the part of the building onto Piazza San Marco and already existed in the Middle Ages when the monastery was inhabited by the Sylvestrian monks. When the monastery was rebuilt in the 15th century, Michelozzo covered the whole area with cross vaults and raised the building to construct the second friars' dormitory. Inside there was also a Pilgrims' Hospice, alluded to in the fresco painted by Fra Angelico on the second door, Christ the pilgrim welcomed by Dominicans. Today it is the home of almost all of Angelico's panel painting, coming from the churches and monasteries of Florence.
“Lavabo” Room and Fra Bartolomeo Room
This room, known as the “Lavabo” Room due to the ancient function for which it was originally equipped, is also accessible from the cloister and is in front of the Large Refectory, next to the kitchen. Monastery rules imposed the ritual washing and purification of the hands before eating. Above the entrance door is a badly deteriorated fresco by Fra Angelico depicting Christ in Pietà, alluding to the Resurrection awaiting those who nourished by him. Today the room contains works presenting the artistic activity of the second great painter who lived in San Marco at the beginning of the 16th century: Fra Bartolomeo. He kept a painting studio in San Marco until his death in 1517. Basing his work on the preliminaries of rational 15th century classicism, Fra Bartolomeo developed a style of art which was freer in its use of colour space and design and inspired the young Raphael. Another door into a room used in the past as the monastery’s kitchen, located in an area containing all of the service rooms, in the vicinity of the “Spesa” Cloister. Today it contains an important collection of painting by Fra Bartolomeo.
