Skansen Kronan is a redoubt built in the later half of the 17th century according to the plans of Erik Dahlberg. Skansen Kronan was introduced in 1698 and was fitted with 23 guns. The roof was not completed until 1700. Skansen has 4-5 metre thick walls made of granite, gneiss and diabase. Skansen Kronan was never attacked and the cannons on the inside have never been used.
The fortress and the twin counterpart, Skansen Lejonet, were built as part of the defenses against possible Danish attack on Gothenburg from the south, and thus had a similar purpose as the Älvsborg Fortress.
The fortress - originally built outside the city walls - is today situated in the city centre of Gothenburg on a hill in the city district of Haga. It was used as a military museum until 2004. Today Skansen Kronan is a private facility for conferences and private parties.
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.
