The famous Kvitsøy Stone Cross was erected between 800–1050 AD. Some say it was put there by English missionaries in the 900s while others claim it was raised by Erling Skjalgsson and Olav Haraldsson, Viking chiefs, in 1016. There are a number of large stone crosses along the west coast of the Norway. Kvitsøy is first mentioned in the Snorre Saga, where Snorre records a truce being made between King Olaf II of Norway later to be known as St. Olav (Hellige Olav) and Erling Sjalgsson, under the stone cross.
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.
