St Catherine's Church is the oldest church in Gdańsk. The first record dates from 1185, when Prince Sobieslaw I built a wooden church. It was replaced with a stone church in 1227-1239. St. Catherine’s church evolved over centuries and only reached its final shape in the mid-15th century. It was a Protestant church from 1545 until 1945, after which it became a Roman Catholic church. There are several magnificent details in the church, like Anton Möller’s triptych painted in 1563-1611.
The tower was destroyed in 1945 in World War II, but rebuilt again in the following decades. Today the church hosts a Tower Clock Museum.
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.
