St. Georg's Church is one of twelve Romanesque churches in the city of Cologne. The date of the foundation of St Georg's is unknown, but it was consecrated towards the end of the 11th century. 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. The church was damaged during World War II, resulting in extensive restoration which included the removal of the Baroque extension to the westwerk and replacement with a simple hip roof in the Romanesque style.
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. The nave is unique in Cologne in having its arcade supported on columns rather than piers.
There is a robust westwerk with walls of 5 metres thick, suggesting that it was intended to be much taller than actually built. The original Romanesque roof of the westwerk was replaced with a Baroque belfry, but this was damaged during World War II and later replaced with a steeply pitched hip roof of copper. During the late 1920s the church had been entirely glazed by the Expressionist artist, Johan Thorn Prikker. These windows were lost during the war, but have been reproduced from the original cartoons.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
