St. Georg is a church and Protestant parish in Aplerbeck, now part of Dortmund, North Rhine-Westphalia, Germany.

[1] In the 19th century when the town grew due to industrialisation, a larger church was built, and St. Georg fell into disrepair.

A plan to make it the centre of a community hall with a restaurant, or a museum, was declined by the conservator (Landeskonservator) Johannes Körner, who demanded that the Romanesque building should be restored without alterations.

He could not prevent the building of a war memorial with a sculpture of Michael the archangel next to the steeple, which led to the name "Michaelisbau".

[2] It serves as the main parish church, after declining attendance failed to fill the Große Kirche for regular services.
