Housed in a former monastery erected between 1437 and 1452 by Michelozzo, an architect held (like Brunelleschi) in high esteem by the Medicis, it has frescoes by Ghirlandaio, Fra’ Bartolomeo, as well as many paintings of his followers. The dormitory cells are fully decorated with frescoes by Beato Angelico, not to mention those which belonged to Cosimo the Elder, the tycoon of the Medici family who paid for the rebuilding of the Church as well as the monastery, which were falling apart in the 15th century. One of the highlights of the museum is the Annunciation fresco on top of the staircase leading to the dormitories, a symbol of purity, obedience, and faith. Very impacting is the Library Hall, also commissioned to Michelozzo and considered one of the best examples of Renaissance interiors, with its arcades supported by narrow pillars with Ionic capitals.
