The Baptistery of San Giovanni ad Fontes is a religious edifice in Lomello. 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 interior is wholly plastered, and can be accessed from two portals. 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.
The baptistery has an elevation of 13 m and is entirely built of brickworks, parts of which date to the 5th-6th centuries. The dome is a later addition (c. 10th century), and was built using less precious materials.References:
The city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
