The Basilica of Saint Denis is a large medieval abbey church in a northern suburb of Paris. The building is of unique importance historically and architecturally, as its choir completed in 1144 is considered to be the first Gothic church. The site originated as a Gallo-Roman cemetery in late Roman times. The archeological remains still lie beneath the cathedral; the people buried there seem to have had a faith that was a mix of Christian and pre-Christian beliefs and practices. Around 475 St. Genevieve purchased some land and built Saint-Denys de la Chapelle. In 636 on the orders of Dagobert I the relics of Saint Denis, a patron saint of France, were reinterred in the basilica.
The basilica became a place of pilgrimage and the burial place of the French kings, with nearly every king from the 10th to the 18th centuries being buried there, as well as many from previous centuries. Saint-Denis soon became the abbey church of a growing monastic complex.
In the 12th century the Abbot Suger rebuilt portions of the abbey church using innovative structural and decorative features. In doing so, he is said to have created the first truly Gothic building. Before the term 'Gothic' came into common use, it was known as the 'French Style' (Opus Francigenum). The basilica"s 13th-century nave is also the prototype for the Rayonnant Gothic style, and provided an architectural model for cathedrals and abbeys of northern France, England and other countries.
As it now stands, the church is a large cruciform building of 'basilica' form; that is, it has a central nave with lower aisles and clerestory windows. It has an additional aisle on the northern side formed of a row of chapels. The west front has three portals, a rose window and one tower, on the southern side. The eastern end, which is built over a crypt, is apsidal, surrounded by an ambulatory and a chevet of nine radiating chapels. The basilica retains stained glass of many periods (although most of the panels from Suger"s time have been removed for long-term conservation and replaced with photographic transparencies), including exceptional modern glass, and a set of twelve misericords.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.
