Valdemars Castle was built by King Christian IV (1588–1648) between 1639 and 1644. It is designed by Hans van Stenwinkel. The king’s plans for his new castle were that the house should become the home for his son Valdemar Christian, who was born to him by Kirstine Munk. King Christian was renowned for his interest in building. On the island of Tåsinge, belonging to his mother in law Ellen Marsvin, the king decided to build a castle for his young son. However, Valdemar Christian never moved in. He was killed in battle in Poland in 1656.
In 1678 the naval hero, Admiral Niels Juel, was given title to the castle and the land on Tåsinge after his victory over Sweden in the Battle of Køge Bay in 1677. The estate was transferred to him as payment for the Swedish ships captured in the battle.
The present owner, Baron Iuel-Brockdorff, who is 11th generation of the Juel family, took over his childhood home from his father in 1971 and lives in the castle with his wife and family. Valdemars Slot has been open to the public since 1974. The castle is open from May to October and on public holidays. The castle features a large chapel, a toy museum, the Iuel-Brockdorff family's big game trophy collection and a local maritime museum. As the castle lies near the beach, it is popular for visitors to come by ferry on the Helge from Svendborg.
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.
