Galluskirche, Romanesque church in Pappenheim, Germany.

Galluskirche is a three-aisled church in Pappenheim whose core dates from the 9th century, with a massive tower topped by a saddle roof built in the 11th century. The east gable carries half-timbering added around 1450, and the walls hold two stone memorial tablets.

The church traces to a donation of 12 November 802 by the noblewoman Reginsind to the monastery of St. Gallen, whose patron Saint Gallus gives the church its unusual name. The monastery built the single-nave church in the 9th century as Pappenheim's parish church; a reconsecration in 1060 records an 11th-century rebuild. Gothic side aisles, choir, side chapel and sacristy followed between the 13th and 15th centuries. After the Reformation of 1539/1540 it served only as a cemetery church.

The name comes from a donation of 12 November 802 by the noblewoman Reginsind to the monastery of St. Gallen, whose patron is Saint Gall. Since the Reformation of 1539/1540 the church has served only as a cemetery church. On the exterior wall, two stone tablets commemorate the fallen of 1914–1918 and the expulsion of Germans from the Sudetenland in 1945–1946.

The church stands at Dechantshof 8, north of the Altmühl and outside the historic centre, so it is reached on foot from the old town across the river. The surrounding walled cemetery, with its 1692 archway, is entered through the gate; the gravestones of Sophie Hoechstetter (1943) and mayor Beck (1878) lie on the grounds. As an active cemetery church, it is best visited outside funeral services.

The church is three-aisled today, but the side aisles were broken through in the Gothic period as large pointed arches, so the original single-nave hall was widened rather than kept. The east gable carries half-timbering added around 1450, and the massive tower with its saddle roof dates from the 11th century.
