Rømø church was built around 1200 but extended in the 17th and 18th centuries when the island prospered due to whaling. The church is consecrated to the patron saint of sailors, St. Clemens and many ship models, donated by seamen, are hanging in the church. During the last century, rights to have one's name on a church pew were sold, the proceeds being used for church expenses, and many of these can be seen on the pews in the church today. Very interesting churchyard with old headstones of the ship commanders and their families, British and German pilots from World War II.
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.
