Lomello Baptistery of San Giovanni ad Fontes

The Baptistery of San Giovanni ad Fontes is a religious edifice in Lomello, Lombardy, northern Italy.

An example of Romanesque-Lombard architecture, it is annexed to the basilica of Santa Maria Maggiore, another early Middle Ages structure.

The baptistery has a typical cross plan, but in the interior the central part forms an octagon, over which is a dome of the same shape.

The baptistery has, on the east-west axis, an overall length of 16 m. The main element is the baptismal font, dating to the 7th-8th centuries.

[1] The baptistery has an elevation of 13 m and is entirely built of brickworks, parts of which date to the 5th-6th centuries.
