Constructed upon a previous building dating back to the IX
th century, San Cristoforo di Lammari hasn't preserved any traces of that ancient structure. The new church, built between XI
th and XII
th century has a
Latin cross plan, three
aisles and a semicircular
apse. Slightly later the bell tower was constructed and the right side of the church was elevated. In the XVI
th century the building was renovated according to the new precepts of the Counter-Reformation: a vaulted ceiling replaced the previous one supported by
trusses and new altars were inserted. In the XVIII
th century the belfry was rebuilt, while in the XX
th century the building was restored to its original medieval appearance. The church has rich sculpted decorations and a series of receptacles for terracotta bowls on the crowning of the apse.
