St. Marien und Andreas, Gothic church in Rathenow, Germany.

St. Marien und Andreas is a Gothic brick church in Rathenow with a four-bay, three-aisle hall and a polygonal choir of seven sides of a dodecagon. The nave has round pillars with spiral bands of glazed brick, and the 75.40 m west tower, rebuilt in 2001, has an observation platform at 51 m.

A late Romanesque brick basilica from around 1190 stood here first; parts of its transept survive in the masonry. From the second half of the 14th century a new choir with ambulatory and seven-sided polygonal close was built, its plan probably modelled on St. Nikolai in Spandau. Between 1517 and 1562 Master Andreas Lindemann rebuilt the nave as a late Gothic hall church, moving the aisle walls into the line of the former transept facades.

The church serves the local Protestant congregation as a place for regular worship and gatherings. It remains an active part of spiritual life in Rathenow and belongs to the regional Protestant church network.

Church visits and the tower climb are possible daily until 5 p.m.; the tower platform stands at 51 m, reached via the 75.40 m west tower. The interior was extensively renovated in 2024, when six column bases of the original ambulatory choir were uncovered.

The tower lost its upper storey in 1972 and was rebuilt in September 2001; its spire was assembled from three segments using a helicopter. The viewing platform at its base stands 51 m up in a tower 75.40 m tall. During 2024 renovation work, six column bases of the original ambulatory choir were uncovered.
