St. Lorenz Basilica is a baroque minor Basilica and the former abbey church of the Benedictine Kempten Abbey. A church was built on the site in the 13th century but was burned down in 1478.
Roman Giel of Gielsberg, the Abbot of Kempten, commissioned the master builder Michael Beer from Graubünden to build a new church to serve the parish and monastery. The foundation stone of the Basilica of St. Lawrence was laid on 13 April 1652. This was one of the first large churches built in Germany after the end of the Thirty Years' War.
Michael Beer built the nave, the ground floor of the towers and the choir. He was succeeded by Johann Serro on 24 March 1654. The church was consecrated on 12 May 1748.
In 1803 the monastery was dissolved and the church became a purely parish church. In 1900 the twin towers were finally completed. They were build of concrete which is heavier than the used material before that time. Cracks at the connections to the main building are the result of the completed towers.
In 1969 Pope Paul VI bestowed the honorary title of basilica minor.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.
