Parish Church of Saint John and Saint Ermolao

The Parish Church of Saint John and Saint Ermolao is a Romanesque house of worship featuring a facade organized in two levels of blind arches and a square bell tower. Inside, granite columns with Ionic and Corinthian capitals divide the space into three naves.

The building was constructed in the 11th century and expanded significantly in 1111 following the arrival of relics attributed to Saint Ermolao from Constantinople. This addition elevated the church's importance in the wider region.

The church honors two saints whose veneration shaped local faith practices over centuries. Visitors can observe the layers of religious art throughout the interior, each piece reflecting the spiritual needs of different generations.

The church is located at Via Don Minzoni 47 in Calci, within walking distance from the town center. Visitors should note this is an active house of worship and visiting hours should be checked in advance.

The baptismal font is carved from a single marble block and displays four basins decorated with 12th-century reliefs. These reliefs were created by the Biduino workshop, making the font one of the most notable artworks in the church.
