The parish church of San Piero in Campo, located at the foot of Montecarlo’s castle, is mentioned for the first time in 846. The building is among the first to be mentioned in Early Medieval Lucchese documents and it has one of the oldest bell towers in the whole diocese of Lucca. The church was completely rebuilt in the XII century and then, again after the village was destroyed in the XIV century.
In the Middle Ages, the isolated church of San Piero in Campo had jurisdiction over a wide portion of the territory. The core of a village gradually developed around it, which was later destroyed in the XIV century. Today, the bell tower is the oldest part of the whole complex and thanks to a comparison with other Lucchese buildings, such as San Martino in Ducentola of Capannori and San Giovanni e Santa Reparata of Lucca, we can suppose that it dates back to the Early Middle Ages.
The present day church, which has been left virtually untouched since the XIV century, has three aisles and a single apse. The façade is crowned by a series of blind arches and a small loggia placed above the mouldings. In Modern times, only a few changes have been made. For example, the bell tower was raised with bricks covered by plaster; today, they are in poor condition. Visitors to San Piero in Campo will undoubtedly be impressed by the remarkable XVI century font located inside the church.
