St. Petrus Canisius

The church was conceived as the central building of the estate planned from 1926 onward, among others by the non-profit housing company GAG, in the Buchforst area then still called Kalkerfeld. For the first time, Riphahn and Grod could design a church in harmony with the surrounding residential architecture. A first design was rejected by the church authorities; only the second version, in the forms of the New Building yet with references to traditional church architecture, was carried out. The consecration took place on 15 February 1931. Much of the church was destroyed between 1942 and 1944. During the 1948 reconstruction by Gottfried and Dominikus Böhm the apse windows were omitted and their niches walled up. In 1992 Maria Schwarz redesigned the interior and parts of the furnishings. The formerly independent parish was merged in 2006 into the new parish of St. Mauritius Köln-Buchheim/Buchforst.

The original apse windows followed a design by Franz Wilhelm Seiwert but were not replaced during reconstruction. The stained-glass windows newly created in 1957 by Wilhelm de Graaff are largely figurative: the aisle windows show scenes from the life of Petrus Canisius, in reds and greens on the north-west side and blues on the south-east, while the surviving chancel windows depict the twelve Apostles. Surviving pre-war pieces include the tabernacle by Eduard Schmitz and two statues by Josef Reimann from 1937. As a tower crown, Heribert Calleen created a twelve-metre cross with a tiara in 1962, which had to be temporarily removed in April 2009 after its mountings had rusted through. Maria Schwarz designed the tabernacle stele, ambo and altar table in 1992. The two-manual organ with 28 stops was built by Willi Peter in 1968. The three bells cast in 1930 were destroyed in the war; the present five-bell peal was cast in 1957 by Wolfgang Hausen Mabilon.
