Built in the 16-17 C, it has an interior of pure and austere lines. To the left of the doorway, the recumbent figure of Bartolomeo Aragazzi is by the Florentine architect Michelozzo and formed part of a tomb whose other element have been dispersed: the two statues which flank the main altar and the bas-reliefs of the first two pillars come from it. Attractive terracotta by Andrea Della Robbia above the baptismal fonts and monumental retable by Taddeo di Bartolo (1401).
