The first mention of the former manor house of the Lords of Velen dates back to 1240. It was not until 1426 that the property with the central wing built at that time was given the title of 'castle'.
In the following centuries, the most famous architects of the region gave the moated castle their signature: Master builder Ambrosius von Oelde, Johann Conrad Schlaun , Ignaz Franz von Landsberg-Velen, painter August Reinking, the Düsseldorf garden artist Maximilian Friedrich. All of these master architects designed the harmonious ensemble of the moated castle, from the courtyard front to the south wing and the castle park, until the 19th century.
Although all this art was largely destroyed by a fire in 1931, it was rebuilt with some internal changes. During and after the Second World War, the building served various public purposes. From 1988 to 2018, Schloss Velen was operated as a sports hotel. Today, the building houses a well-equipped seminar and conference centre.
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.
