In 1410 St.Christopher's church was moved to the market square, inside the new town wall. The church was badly damated during the Second World War. The tower was one day before the liberation blown up by the Germans and rebuilt after the war in modified form. On 13 April 1992 caused an earthquake in Roermond for significant damage.
On top is a huge statue of St. Christopher watching over Roermond. Today the cathedral is the main church of the Roman Catholic Diocese of Roermond.
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.
