Marienkirche, Gothic church in Bernburg, Germany.

Marienkirche is a three-aisled, five-bay Gothic hall church with a two-bay single-nave choir closing in five sides of a dodecagon. Its oldest part is the lower storey of the massive west tower, built of ashlar masonry in the mid-13th century; the choir, renewed around 1420/40, carries finely carved tracery and hanging arches. The nave has a Baroque pointed barrel vault, and a stone gallery of 1555 stands in the west bay.

The oldest part is the lower section of the west tower, built of ashlar masonry in the mid-13th century; a 1228 document may refer to the church, though this is disputed. The tower was completed in the first half of the 14th century, the nave followed in the second half, and around 1420/40 the two eastern bays and the choir were rebuilt. The choir vault was largely renewed in 1868, and restoration work continued after 1971.

The church belongs to the Talstadtgemeinde Bernburg of the Evangelical Church of Anhalt, a Lutheran regional church, not a Reformed congregation. Its name refers to Mary, and the 1555 stone gallery in the west part of the nave still marks where the congregation sat. The organ, rebuilt 2017–2020 behind the restored 1902 facade, can be entered.

The location is regularly open for religious services, festivals, and cultural events, allowing visitors to see the interior. It is helpful to check in advance whether an event is happening so you can enter without disruption.

The organ, rebuilt from 2017 to 2020 by Orgelbau Hüfken, has 37 stops on three manuals and pedal and is walkable inside. Parts of a Röver instrument damaged by fire in 1976 in Alsleben were reworked and reused behind the restored 1902 case.
