Dorfkirche Arensberg, Romanesque church in Arensberg, Germany.

The Dorfkirche Arensberg is a small Romanesque hall church of rough fieldstone, with a lower nave and a west cross-tower whose steep gable roof carries arched sound openings. The nave has a red tiled roof, narrow windows and a lower annex at its far end; a low stone wall runs in front. The windows were enlarged in the rebuild of 1800/1807, but the round-arched east window, the fieldstone priest's door on the north chancel side and the pointed nave portal with stepped brick jambs survive.

Built in the first half of the 13th century as a small Romanesque fieldstone hall church with a nearly square choir and a west cross-tower. A major renovation in 1800/1807 enlarged the windows. In the 19th century a massive pillar was added to the tower's west wall to support its two fieldstone barrel vaults.

The winged altarpiece, carved around 1480–1490, shows Mary on the crescent moon held by two angels, flanked by Saint Christopher and Saint James the Greater, with the twelve apostles on the wings. A bell cast by Arndt Blome in 1525 hangs in the tower. The vault paintings, uncovered in 1933–1935, depict the Gnadenstuhl and the four evangelists.

The church stands in the village of Arensberg, part of Bismark (Altmark) in the Stendal district, and belongs to the Bismark parish of the Evangelical Church in Central Germany. The nave is flat-ceilinged and the chancel is closed by a domed cross-ribbed vault of fieldstone, so the interior is compact and quickly seen. A massive pointed arch separates the nave from the tower room, and a round-arched triumphal arch separates it from the chancel.

During restoration work in the 1930s, hidden wall paintings from the 15th century were discovered beneath later layers. These artworks reveal details about the original layout and decoration of the space in medieval times.
