Gartenstadt-Nord, Residential condominium complex in Longerich district, Cologne, Germany.

Gartenstadt-Nord is a large residential estate in the south of Cologne's Longerich district. Its first section, built in 1936, consists of single-family houses with large gardens. The later Katholikentagssiedlung, laid out from 1957, mixes five house types of 93–105 m², three-story six-family buildings and Y-shaped point houses around Altonaer Platz, which is lined with two-story buildings housing shops and restaurants.

The first Gartenstadt-Nord settlement was built in 1936, with large gardens for residents' vegetable growing. From 1957, the Katholikentagssiedlung extension arose on the southwestern edge of Longerich; the first spade was turned on 16 July 1956 by district president Wilhelm Warsch. It was inaugurated on 12 September 1959 by Archbishop Josef Cardinal Frings, and its church St. Bernhard followed two years later.

Many streets in the south-western part of the settlement are named after resistance fighters of the Nazi era, including the Geschwister-Scholl-Straße and the Stauffenbergstraße. The settlement itself is commonly called Katholikentagssiedlung, after the 1956 Katholikentag in Cologne, when the first sod was turned.

The settlement lies in the south of Longerich, with Altonaer Platz as its centre; the streets around it are named after northern German cities such as Altona, Cuxhaven and Osnabrück. The 1950s section is bounded by Longericher Straße and An der Ling, and many of its streets honour resistance fighters of the Nazi era, among them Geschwister Scholl, Julius Leber and Pater Delp.

The streets built in the late 1950s were mostly named after resistance fighters of the Nazi era, among them Christoph-Probst-Straße, Geschwister-Scholl-Straße and Stauffenbergstraße. The Ossietzkystraße was added later as the access road to the newly built Catholic elementary school.
