You can't talk about San Marco without talking about the Medicis. It was in fact Cosimo il Vecchio, grandfather of the Magnifico, who entrusted his trusted architect Michelozzo with the restructuring of the convent, a place that was particularly dear to Cosimo and to which he often went. For this reason, two of the 46 cells of the Dominican friars were destined to him, where one can admire the splendid fresco decorations made by the friar-painter Beato Angelico. In the corridor is his masterpiece, one of the most famous frescoes in the world, the famous and delicate Annunciation. Among the cells are those of the friar Girolamo Savonarola, with part of his habit, a famous portrait of him and the painting depicting the stake in Piazza della Signoria that portrays him during the public execution. His capture in the convent (for accusing the Church of corruption and immorality) was announced by the bell of St. Mark's, which rang in the middle of the night in an attempt to summon the faithful to save him.
