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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
