It has a fine Renaissance facade, constructed about 1500 by Cardinal Giovanni de' Medici (afterwards Pope Leo X.), and some good terra cottas by the Della Robbia.
The interior is spacious and contains some fine 14th-century sculptures, those of the high altar, which contains the tomb of St Donatus, the patron saint of Arezzo, being the best; very good stained-glass windows of the beginning of the 16th century by Guillaume de Marcillat, and some terra-cotta reliefs by Andrea della Robbia.
Within is a beautiful group of the Visitation by Luca della Robbia.
The reliefs consist of a series of groups representing the Seven Works of Mercy and other figures; these were executed by Giovanni Della Robbia between 1514 and 1525, and, though not equal to the best work of Luca and Andrea, are yet very fine in conception and modelling, and extremely rich in their general decorative effect.
A mile and a half to the north-east is the handsome early Renaissance pilgrimage church of the Madonno della Quercia; the façade is adorned with three lunettes by Andrea della Robbia.
