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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
