About the Baptistery of Neon

The Baptistery of Neon, known too as the Orthodox Baptistery, is a Roman religious structure in Ravenna, in northeastern Italy. It is the oldest monument left in the city, and part of it was built where a Roman bath once stood. Bishop Ursus began the octagonal brick building in the late 4th or early 5th century, as part of a great basilica that was destroyed in 1734.

Bishop Neon completed the baptistery late in the 5th century and added its mosaics. The eight-sided plan, used in nearly every Early Christian baptistery, stands for the week's seven days and for the Resurrection and eternal life. Inside, John the Baptist appears in the ceiling mosaic, baptizing Jesus waist-high in the Jordan River, with Zeus personifying the river, while a procession of the twelve apostles moves in two directions and finishes as Saint Peter meets Saint Paul.

The original floor lies about 3 meters below ground. Ravenna has eight structures on the UNESCO World Heritage list, and this is one of them. An ICOMOS assessment called it the finest, most complete surviving example of an early Christian baptistery.
