The city church of St. Mary's is in Fürstenwalde (Spree) since the papal confirmation in 1385 seat of the bishops of the diocese of Lubusz.
The bishops have since been buried here as well. 1432 was the destruction of the city church, so that - starting in 1446 - was a new building as a cathedral. 1528 plundered the robber baron Nickel von Minckwitz with his troops the cathedral. 1555 died with Bishop John VIII Horneburg, the last Catholic bishop of Lubusz. On April 12, 1557, in the presence of Elector Joachim II and his brother Hans von Küstrin, the first Protestant church service took place in this cathedral as margrave of Neumark.
Remarkable pieces of equipment are a free standing and towering sandstone sacrament house dated 1517 and bearing the signature "FHM", and the tomb of Bishop Dietrich von Bülow, who was created with the same signature and created after his death in 1523. The earlier assumption that both works were created by the Freiberg sculptor Franz Maidburg (c. 1480-1533) proved to be erroneous.
In 1771, the formerly Gothic church was radically baroqueized. The vaulted ceiling, the cathedral cladding, the tower and the exhibits were completely redesigned.
In the years from 1908 to 1910, the cathedral was restored and the baroque church rebuilt into a Gothic one. The glass painting workshop Rudolf and Otto Linnemann created 1910 a window with the representation Christ with Maria and Martha and a window with ornamental painting.
