Description
The baptistery of St John was built by Constantine on the site of a Roman nymphaeum in the Lateran Palace. This octagonal building, the oldest baptistery in Christendom, provided a model for later baptisteries. The doors of the chapel of St John the Baptist emit a ringing sound when they are opened or closed.
