With its cloister and Chapter House, Saint-Gaudens Collegiate Church was one of the most important religious buildings in the Comminges area. It was home to a College of Canons Ordinary, a community founded by Bishop Bertrand.
The 11th century Romanesque church, built on the typical Pyrenean plan as a basilica with three naves, stands on the site of an earlier construction. It was extended in the 12th and 13th centuries with the construction of the cloister and Chapter House. The lateral North Door was added in the 16th Century.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.
