San Giusto Vecchio, Romanesque church in Suvereto, Italy.

San Giusto Vecchio is a single-nave Romanesque church with a transept, rebuilt in 1189 by Barone Amico and Bono da Calci. Its facade has a portal flanked by two columns with capitals supporting lions, a bichrome archivolt with spirals, and a quadrilobate eye above. Inside is an octagonal late-medieval baptismal font.

The pieve is documented from 923 and likely has early medieval origins. It was rebuilt in 1189 by the master builders Barone Amico and Bono da Calci, as an inscription on the left transept's plaster records. Its Pisan character appears in the decoration and in the single-nave plan with a transept.

The name San Giusto refers to Saint Justus, to whom the pieve is dedicated. The church stands on piazza Vittorio Veneto, and its left transept preserves the 1189 inscription naming the master builders Barone Amico and Bono da Calci. Inside, an octagonal baptismal font from the late Middle Ages marks the baptismal rite.

The church is easy to find on foot in Suvereto and allows visitors to examine the architecture up close. The exterior is accessible from all sides, making it possible to view the Romanesque details from different angles.

On the left transept plaster an inscription names the builders Barone Amico and Bono da Calci and the year 1189, when the church was rebuilt. The facade portal is flanked by two columns whose capitals carry lions, and above the architrave sits a two-coloured archivolt with spiral ornament.
