Kirchenruine Nordhusen, Romanesque church ruin in Haldensleben, Germany.

Kirchenruine Nordhusen is the roofless west transverse tower of a former village church, standing 17 m tall on a grassy rise near Hundisburg. Its walls of regularly cut greywacke rubble measure 11.80 by 5.20 m in plan. The fully preserved east wall holds two round arches toward the former nave and five sound openings; the north and south sides each have two more. A small white sign is fixed at the lower left corner.

The church was built around 1200, but the local population relocated to Hundisburg by 1214. This move led to the gradual abandonment of the settlement and the partial preservation of the structure.

The ruin is a station on the Straße der Romanik, the tourist route linking Romanesque buildings in Saxony-Anhalt, and part of the Ecomusée Haldensleben-Hundisburg. The name Nordhusen survives only as a deserted settlement site (Wüstung) beside Hundisburg, whose chapel of 1218 began as a branch of this church.

The site is freely accessible and can be viewed from the outside, making it easy to explore on foot. Visitors who want more information can visit the Tourist Information Center at Bahnhofsplatz in Haldensleben.

The tower's completely preserved east wall holds two round arches that once opened into the former nave, plus five sound openings; the north and south sides each have two more. The ruin is a station on the Straße der Romanik and part of the Ecomusée Haldensleben-Hundisburg.
