One of the largest rocks of Nordic Bronze Age petroglyphs in Scandinavia is located in Tanumshede locality, Tanum Municipality. In total there are thousands of images called the Tanum petroglyphs, on about 600 panels within the World Heritage Area. These are concentrated in distinct areas along a 25 km stretch, which was the coastline of a fjord during the Bronze Age, and covers an area of about 51 hectares. Tanumshede rock carvings have been declared as a World Heritage Site by UNESCO.
Scandinavian Bronze Age and Iron Age people were sophisticated craftsmen and very competent travelers by water. (Dates for ages vary with the region; in Scandinavia, the Bronze Age is roughly 1800 to 500 BCE) Many of the glyphs depict boats of which some seem to be of the Hjortspring boat type carrying around a dozen passengers. Wagons or carts are also depicted.
Other glyphs depict humans with a bow, spear or axe, and others depict hunting scenes. In all cases the pictures show people performing rituals. There is a human at a plough drawn by two oxen, holding what might be a branch or an ox-goading crop made of a number of strips of hide.
The rock carvings are endangered by erosion due to pollution. To the dismay of some archaeologists, some have been painted red to make them more visible for tourists.
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.
