San Giorgio in Braida church was built in the 16th century in the medieval quarter of Veronetta. The 12th-century bell tower is what remains of a monastery built in the 11th century. The facade is marble white with two rows of pillars. The statues of St. George and St. Lorenzo Giustiniani are on sides. The interior has a single nave built between 1536 and 1543, and contains key works of art. Above the main door is a Tintoretto painting depicting the baptism of Christ. The church houses Paolo Veronese's masterpiece, The Martyrdom of St. George. In 1540 Michele Sanmicheli built the dome of the church. In 1776 were cast the six bells tuned in the scale of G major, on which was developed the Veronese bellringing art.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.
