Brunelleschi began to build Santo Spirito church in 1444, on the ruins of a medieval convent earlier destroyed by a fire. The church was completed in 1487 by some collaborators, after Brunelleschi's death. Inside it's a clear example of Italian Renaissance architecture, divided in three naves by columns of typical florentine stone, Baroque decorations and 38 family chapels with paintings and precious treasures. The altar is covered by a beautiful Baroque canopy with a drilled dome. Inside the sacresty you can find the famous crucifix by Michelangelo, carved when he was only 18 years old. The square outside is a hangout for Florentine life.
