St. Kolumba was one of the largest parish churches in medieval Cologne, dating back to 980, and dedicated to Columba of Sens.

Artworks in it included the Saint Columba Altarpiece by Rogier van der Weyden, and an altar by an anonymous artist.

[1]: 75/76 [2] The church featured notable artworks, such as the Saint Columba Altarpiece by Rogier van der Weyden, a Bartholomäus-Altar by the Master of the Saint Bartholomew Altarpiece, and the Master of the Wasservass Calvary.

Only some exterior walls, the basement of the tower, the entrance hall, and a Gothic statue of Mary survived.
