This church is dedicated to St. John from Jerusalem and was built in 1119 together with the hospitable annex, with a stone gabled facade and a small bell gable. It preserves recently restored frescoes, including the one on the right side of the exterior, depicting St. Christopher (dating back to the 13th century) and the one on the inside, from the first half of the 14th century, depicting Our Lady of Mercy. Among the sculptures there is a Roman altar with reliefs dating back to the 1st century AD of particular beauty, currently used as a holy water font, and three wooden altars, one of which dates back to 1500.
