Göksholm is the oldest privately-owned building in Sweden that has been continuously inhabited.
In the middle ages Göksholm was just a fortified castle with a large tower. Its oldest existent parts have been dated to the 13th century. It was built (rebuilt and enlarged) during the Middle Ages through six different stages.
After a fire at the end of the 16th century, the building was modernized according to that period's style, getting a more regular plan, bigger windows and details in the Dutch renaissance style. Despite the thorough renovation, the medieval base structure remains. A painted inner ceiling from the time of this renaissance renovation exists with 121 cassettes which is remarkably well preserved today.
Under the 17th century owners, Baron Knut Kurck and Baron Fleming, the castle was encrusted with portals, and circle-patterned outer buildings. Lars Gustaf Tersmeden had the ceiling renovated in 1801. This was the last big change in its structure. Some facade details were changed in the 1950s.
Historically Göksholm is famous for the popular uprising's leader Engelbrekt Engelbrektsson, the leader of the government, having been murdered on its lands in 1436 by Måns Bengtsson, the son and heir of the then owner of the castle.
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.
