St. Fronleichnam, Catholic church building in Porz, Cologne, Germany

St. Fronleichnam is a church building in Porz designed by architect Gottfried Böhm between 1958 and 1960. The structure features a rectangular plan with distinctive pyramidal roofs, slender white columns, and large glass windows that flood the interior with natural light.

A parish was founded in early 1958 for the new settlement on former farmland in Porz, and the foundation stone was laid in May 1959; the church was consecrated at Pentecost 1960 after thirteen months of building. The tower, not planned by the archdiocese for cost reasons, was financed by the congregation through a loan. The mother parish St. Bartholomäus in Urbach gave a bell from 1457, five more followed in 1965, and in 1966 the medieval bell was replaced by the Christkönigsglocke for reasons of sound; it now stands in the Porz district council building. The church was listed as monument number 8224 on 22 December 1997 and became a filial church of St. Maximilian Kolbe around 2000.

The parish was founded in early 1958 and used the Franz-Hitze-Haus and a nearby school as temporary churches before the building was consecrated at Pentecost 1960. The name refers to the feast of Corpus Christi. Since a 2000s merger, St. Fronleichnam has been a filial church of the St. Maximilian Kolbe parish, which unites four former independent parishes.

The church stands on a rectangular plot in Porz, ringed by thin white round columns that carry the folded roof; the square tower rises within the same columned enclosure. The glazed wall on three sides is broken by a glass niche with its own pyramidal roof, the baptistery. Since 1997 the building has been listed as monument number 8224 in Cologne's register.

The church was inspired by the idea of a biblical tent and symbolizes God's presence among people rather than in a grand palace. Böhm's design concept uses the roof forms and columns to express this spiritual message architecturally.
