Mostly completed in 1360, work on the church’s interior and exterior ornamentation picked along until the 15th century.
The upper section of the front marble facade as well as the doorway were designed by Leon Battista Alberti (completed around 1470).
The interior nave is an impressive 100 meters (328 feet) long. About halfway up the north (left) aisle is Masaccio’s Trinita fresco. Other notable frescoes include those by Filippino Lippi inside the Capella di Filippo Strozzi (first chapel to the right of the alter).
Go outside the church, following the sign for the museo to find the Green Cloister (Chiostro Verde), which, as advertised, contains primarily green frescoes depicting Genesis.
The Spanish Chapel (Cappellone degli Spagnoli), on the north side of the Green Cloister, is covered in a variety of frescoes by Andrea di Bonaiuto, done in 1365 to 1367.
The museum (entrance fee: 2.70 euros) contains ecclesiastical relics.
