Church of San Francesco Arezzo

The Basilica of San Francesco is a late Medieval church in Arezzo, Tuscany, Italy, dedicated to St Francis of Assisi. It is especially renowned for housing in the chancel the fresco cycle Legends of the True Cross by Piero della Francesca.

San Francesco is the second church built by the Franciscans in Arezzo, an earlier church being located outside the city walls and destroyed during the Occupation. The building work on San Francesco was begun around 1290. The decoration of its façade was never realised.

The interior presents as a large church of simple unadorned design with a wide single nave, flanked on the left side by some chapels and, on the right side, by some niches. The tall groin-vaulted chancel is of square plan.

Beneath the church is a smaller Chiesa inferiore or "Lower Church" as at Assisi, with a nave and two aisles, now used as exhibition hall.
