Sant'Agostino, Church complex in Nicosia, Calci, Italy

Sant'Agostino is a church and convent complex in Nicosia, a hamlet of Calci in Tuscany. The church has a single hall with a pitched roof and a brick bell tower; the interior holds 18th- and 19th-century frescoes and tempera decorations. The convent buildings stand abandoned, overgrown with climbing plants.

Ugo da Fagiano, bishop of Nicosia in Cyprus, had the church and convent built between 1258 and 1264. The Augustinians used the complex until the order was merged in the 16th century with the Regular Canons of San Salvatore in Bologna. A chapel dedicated to the Baptist in this church is the likely origin of Alvaro Pirez's damaged Madonna and Child with Two Angels, now in the Museo Nazionale di San Matteo in Pisa.

The church and bell tower are still used by the parish of Calci, while the rest of the convent complex stands abandoned. From a chapel dedicated to the Baptist in this church came Alvaro Pirez's mutilated Madonna and Child with Two Angels, now at the Museo Nazionale di San Matteo in Pisa.

The complex remains partially operational, with the church and bell tower maintained by the Calci parish while other sections stand abandoned. Visitors should expect that not all buildings may be accessible and visiting conditions may depend on the season.

The church and convent were founded between 1258 and 1264 by Ugo da Fagiano, bishop of Nicosia in Cyprus. A mutilated Madonna and Child with Two Angels by Alvaro Pirez, now in the Museo Nazionale di San Matteo in Pisa, is thought to have come from a chapel dedicated to the Baptist in this church.
