Right outside the cities of Fredrikstad and Sarpsborg in South-East Norway, there are two archaeological, intriguing and beautiful sites, the Hunnfelt, a monument consisting of several stone circles and burial sites, and the Begbyfelt, a large collection of petroglyphs. The sites are encoded with a rich and still not fully understood history stretching from the early Bronze Age (1700-1100 BCE.) to the Viking Age (790-1100 CE).
