Visit the Early Christian Baptistery of San Giovanni in Fonte in Padula with Campania>Artecard, one of the oldest baptisteries in the Western world.

The Early Christian Baptistery is one of the oldest in the Western world. It was built at the request of Pope Marcellus I, from whom the church and the village of Marcellianum take their name. The site was destroyed in the 6th century, possibly during the Gothic War. In the 12th century, the church was rebuilt and dedicated to Saint John the Baptist.

The restoration work carried out between 1985 and 1987 uncovered a structure centered around a square-shaped building, along with walls featuring full arch openings, which likely once supported a dome.
