The original church in the settlement, dedicated to Saint Thomas, was a Romanesque structure with a square nave and a rounded apse. The remains of this are still visible in the corner of the sanctuary. The surviving sanctuary is mostly Gothic, dating to around 1500. The church was rebuilt a number of times, most extensively in 1848 when three layers of frescos were revealed, the oldest dating to the early 14th century, the second layer to around 1400, and the top layer to the early 16th century.[7]
