Tjuvholmen

Tjuvholmen peninsula has played an important role in the history of Hamar. A relatively large memorial mound has been found on the southern side of the island. It is in a location which makes it easy to see for approaching ships, and it has served as a property marker or demonstration of power. The mound also says something about how important Lake Mjøsa was as a transport artery. The memorial mound probably dates from the Bronze Age/Early Stone Age (1800 BC to 500 AD). As its name indicates, the small island of Tjuvholmen (= thieves' island) was used to incarcerate thieves and other villains. The fishermen in Hamarkaupangen lived along the shore of the lake all the way along to the cathedral promontory.

Today, there is a marina and outdoor areas with opportunities for swimming and grilling. Tjuvholmen Kro (inn) is located by the marina and is, in summer season, open every day from 11:00 to 21:00
