The city's Catholic parish church was built from 1317 to 1325 in the brick Gothic style and was consecrated to Mary. It replaced an older chapel of St. Nicholas. Between 1548 and 1550, expansions were made, such as the addition of the church tower, which was connected to the north side of the choir with its stepped gable typical of the landscape. A northern extension was added in 1642 and the vestibule to the west in 1904. Johan Heinrich Selcke from Riesenburg created the main altar in rococo style in 1740. The altar painting, added in 1790, was made by the Berlin painter Bernhard Rode. A wooden crucifix dates from the second half of the 14th century, the bronze altar candlestick from the 15th century. During construction work in 1975, wall paintings from the early days of the building were uncovered. Source: Wikipedia
