The date of the foundation of St Georg's is unknown, but it was consecrated towards the end of the 11th century.
[1] The nave was vaulted in the mid-12th century, the westwerk was added in 1188 and the entrance portal on the north side in 1551.
[1] St Georg's has the trefoil-shaped eastern end typical of other Romanesque churches of Cologne, its chancel and transepts each terminating in an apse.
[1] There is a robust westwerk with walls of 5 metres thick, suggesting that it was intended to be much taller than actually built.
[2] During the late 1920s the church had been entirely glazed by the Expressionist artist, Johan Thorn Prikker.
