Stuttgart Cathedral or St Eberhard's Cathedral has been since 1978 the co-cathedral of the Roman Catholic Diocese of Rottenburg-Stuttgart, whose main cathedral is Rottenburg Cathedral. The parish dates back to the Medieval era while the current building was completed in 1955, eleven years after it was mostly destroyed by Allied air raids in 1944.
Liudolf erected a small church around 950 and remnants of the old collegiate church were discovered under the nave of the current Cathedral. The fortunes of the Cathedral has largely been determined by the religion of the House of Württemberg, who ruled the area which comprises the present-day state Baden-Württemberg, of which Stuttgart is the capital.
In 1808, the foundation stone for the new Catholic church was laid with little fanfare. It was completed in 1811. The rectory and most of the church, along with many important buildings in the city, were destroyed during the bombing of Stuttgart in World War II in 1944.
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.
