The Meissen Cathedral is situated on the castle hill of Meissen, adjacent to the Albrechtsburg castle. It was the episcopal see of the Bishopric of Meissen established by Emperor Otto I in 968. It replaced an older Romanesque church. The present-day hall church was built between 1260 and 1410, the interior features Gothic sculptures of founder Emperor Otto and his wife Adelaide of Italy as well as paintings from the studio of Lucas Cranach the Elder. The first Saxon elector from the House of Wettin, Margrave Frederick I, had the Prince's Chapel erected in 1425 as the burial place of his dynasty. The twin steeples were not attached until 1909.
In 1581 the Meissen diocese was dissolved in the course of the Protestant Reformation, and the church was used by the Protestant Church since. It is the cathedral church of the Evangelical-Lutheran Church of Saxony.
Burials in the Prince's Chapel include many Electors and Dukes of Saxony.
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.
