Schwerin Cathedral was formerly a Roman Catholic cathedral, dedicated to the Virgin Mary and Saint John. It was built in Schwerin following the move here of the seat of the Bishopric of the Abodrites, established by Henry the Lion, from the old city of Mecklenburg in the late 12th century. The first cathedral was built of timber. The foundation stone of the stone cathedral of the Prince-Bishopric of Schwerin was laid in 1172. After a construction period of 76 years, it was consecrated in 1248. The proto-cathedral is now the church of the Bishop of the Evangelical Lutheran State Church of Mecklenburg.
In 1222 Count Henry of Schwerin returned from a crusade with a reliquary of the Holy Blood, an alleged drop of Christ's blood contained in a jewel. This was placed in the cathedral, and caused it to become a place of pilgrimage. During the 14th century the nave and transept were completed, as well as the chapter buildings. At the end of the 15th century the cloister on the north side was finished.
The tower, 117.5 metres high, was constructed between 1889 and 1893.
References:Ogrodzieniec Castle is a ruined medieval castle originally built in the 14th–15th century by the W³odkowie Sulimczycy family. Established in the early 12th century, during the reign of Boles³aw III Wrymouth, the first stronghold was razed by the Tatars in 1241. In the mid-14th century a new gothic castle was built here to accommodate the Sulimczycy family. Surrounded by three high rocks, the castle was well integrated into the area. The defensive walls were built to close the circuit formed by the rocks, and a narrow opening between two of the rocks served as an entrance.
In 1470 the castle and lands were bought by the wealthy Cracovian townsmen, Ibram and Piotr Salomon. Then, Ogrodzieniec became the property of Jan Feliks Rzeszowski, the rector of Przemy¶l and the canon of Cracow. The owners of the castle about that time were also Jan and Andrzej Rzeszowskis, and later Pilecki and Che³miñski families. In 1523 the castle was bought by Jan Boner.
