It was erected during the 14th century in the town of Montecatini Val di Cecina, province of Pisa, in the region of Tuscany, Italy.
In addition the choir was frescoed by an anonymous Sienese painter commissioned by Nicola Nieri of Montecatini.
Flanking the main altar are two marble angels, called ciechini, attributed to Mino da Fiesole.
In the niches above the choir are two terracotta statues by the studio of Della Robbia, depicting Saints Blaise and Sebastian.
