Gudsberga Abbey (Gudsberga Kloster) was a Cistercian abbey established in 1486. It was the last Cistercian abbey in Sweden. Gudsberga owned farms, manors, foundries and mines until 1527, when it was reduced to the Crown during Reformation. In 1538 and 1544 King Gustav Vasa ordered to send silver from abbey to Stockholm. It was demolished later. Today some stone foundations remain and there is a museum exhibiting the forge of abbey.
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.
