Schleswig Cathedral (, ) officially the Cathedral of St. Peter at Schleswig (), is the main church of the city of Schleswig and was the cathedral of the Bishop of Schleswig until the diocese was dissolved in 1624. It is now a church of the North Elbian Evangelical Lutheran Church, the seat of the Lutheran Bishop of Schleswig and Holstein, and ranks among the most important architectural monuments of Schleswig-Holstein. History Predecessors In 850 a missionary church was founded in Haithabu (Hedeby). Between 947 and 949 Otto I installed three dioceses on the Cimbrian peninsula: Ribe, Schleswig and in 948 Århus. After the foundation of the Schleswig diocese in 947, the first cathedral in Schleswig was built. Today, neither the size nor the location of this cathedral is known.

After the collapse of two towers and some parts of the basilica in 1275, the High Gothic Hall Choir was constructed and completed around 1300. The Late Gothic Hall Church was built from 1200 to 1408 and was finally completed in the 16th century. In 1894 that the cathedral got its final outward appearance. In 1879 Schleswig became the provincial capital in 1879, and in 1888 the construction of a Gothic revival western tower began at the request of the King William II of Prussia. It was completed in 1894 and at 112 metres, a little too high compared to the proportions of the cathedral. There is a viewing platform on the tower at 65 metres which commands a
