Arresødal was created as a manor in 1773 by Major General Johan Frederik Classen. He ordered the building of the main house in 1786-1788. Upon his death, Classen bequeathed Arresødal to Prince Charles of Hesse-Kassel, who owned the property until Crown Prince Frederik (later King Frederick VI of Denmark) bought the property in 1804. The main building was rebuilt in 1908-1909 and partly in 2004. Two other buildings on the estate are protected.
In 1883 the property was purchased by the Classen Fideicommis. It was then a convalescent home for women until 1944 when it was taken over by first the Germans and then the freedom fighters who used the buildings as a prison. It once again became a convalescent home until 1984 when Arresødal was sold to KMD Kommunedata.
Today Arresødal functions as a private hospital. The park is now open to the public.
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.
