The church of San Prospero, whose origin is uncertain, in 1543 risked falling into ruins. In 1705 the structure of the church was based on a small, squared nave covered by plates. At the end of the XIX century the building was unstable because of the soil from landslides. The antique church of San Prospero of Valbona, which rose on the eastern border of the village, collapsed after the 1920 earthquake. A large landslide destroyed a second building, which had been built afterwards. The interior of the present day church retains two praiseworthy full relief statues made of Lunese marble dating back to the XVII – XVIII century.
