St. Georg, Aplerbeck, Romanesque church building in Aplerbeck, Dortmund, Germany

St. Georg is a Romanesque cross basilica of rough grey-brown stone, built between 1150 and 1160. It has a central nave, two side aisles, a transept, a square west tower with a steep pyramidal roof, and a flat-ended choir. The massive tower, added around 1300 from unhewn bog sandstone, was originally windowless, with only arrow slits.

A church in Aplerbeck was first documented in 899, when Wichburg granted the parish priest Radboldus a benefice in her donation to St. Gereon in Cologne. The present Georgskirche was built between 1150 and 1160 as a Romanesque cross basilica; traces of the earlier building were found during the 1963 restoration and 1992 trial digs. Around 1300 a defensive west tower of rough swamp sandstone was added, and Gothic rebuilding was completed by the altar endowment of 1404. The parish became Lutheran in 1612.

The parish became Lutheran in 1612, when Nicolaus Witthenius signed the Augsburg Confession for the synod of the County of Mark. Since 1999 the larger Große Kirche has served mainly for concerts, while St. Georg again holds the regular services. The street beside it is still called Ruinenstraße, named for its years as a ruin.

The tower entrance originally sat about two metres above today's main door, so the west portal is the way in. The church stands on Ruinenstraße, named for its years as a ruin; the war memorial with the archangel Michael sculpture stands beside the steeple. The parish shares Aplerbeck with the Große Kirche, mostly used for concerts since 1999.

The tower was added around 1300 as a defensive structure, built of rough swamp sandstone with only arrow slits and an entrance about two metres above today's main door. A war memorial with a sculpture of the Archangel Michael was placed next to the steeple, giving the building the nickname "Michaelisbau".
