The Parish Church of San Piero in Campo in Montecarlo was isolated from the nearest towns in the Middle Ages, with its jurisdiction extending across the territory, gradually becoming the centre of a small settlement that was destroyed in the 1300s.
The bell tower is the oldest part of the complex and can be dated to the Middle Ages based on other similar structures in the Lucca area, like Martino in Ducentola in Capannori and San Giovanni e Santa Reparata in Lucca.
The church as we see it today is mostly intact from the 14th century and vaunts three naves and a single apse. The façade bears a series of blind arches along the top and a small loggia above the cornice.
One of the modern renovations included raising the brick bell tower, which is covered in a badly-conserved layer of plaster. The baptismal font from the 16th century inside the church is worth seeing.
