Saint Giles Church on the Kostelní Square in the centre of Nymburk was built probably in the 13th century, as well as the surrounding town. However, there are no preserved sources confirming its origins. The church is a three nave basilica with a long chancel and a tower in the front. There was also a second tower, but now there are only its remains.
The temple is an example of brick Gothic architecture, except of a few parts which are made from sandstone. Its thin tower reaches 66 metres and together with mediaeval ramparts creates a characteristic silhouette of the town. The dean's church was initially dedicated to Saint Nicholas, during the Thirty Years' War the dedication changed to Saint Giles. The church is a cultural monument of the Czech Republic.
The church has many interesting and valuable things inside. The most valuable one is a plastic of the first patron St. Nicholas, made of stone. The plastic probably came from the workshop of a sculptor Peter Parler (the 14th century) but it might be even older than that. Most of church's equipment is in the Baroque style. The main altar in the front is from 1704.
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.
