A city in Norway founded in 997 by King Olaf I Tryggvason; he built a church and a royal residence, Kongsgård, there. The pottery, glass and coins from the excavations indicate that the site flourished in the 9th century. Like Hedeby and Birka, Kaupangr seems to have maintained extensive contacts with the Franks and Slavs as well as sustained links with the Arab world.
