Aplerbeck is a borough (Stadtbezirk) of the city of Dortmund in the Ruhr district of North Rhine-Westphalia, Germany.

A psychiatric hospital of regional importance, founded in 1890, is still in operation, now as LWL-Klinik Dortmund [de].

[citation needed] In 1890, the Prussian state government chose Aplerbeck as the home of a new psychiatric clinic to serve the Ruhr area.

[5] The Georgskirche is a Romanesque church which is first mentioned in a document in 1147, but probably is based on an older building from the 9th century.

[6] The Große Kirche Aplerbeck was built in Gothic Revival style after a design by Christian Heyden from 1867 to 1869.

[6] As many people of Polish origin settled in Aplerbeck, they needed a Catholic church, which was built after a design by August Carl Lange [de] and consecrated on 21 December 1880, named St. Ewaldi [de] after the martyrs.
