Skien was an important area of settlement and activity in the Grenland region as early as the Viking Age around the year 1000, with evidence of trade, movement, and continuous habitation. Archaeological finds at Faret reveal early Christian activity through one of Norway’s oldest churches, earlier post-built churches, and an extensive burial ground containing both Christian and pre-Christian graves. On Kapittelberget, the remains of an early medieval church attest to continuity in power and religious significance. Taken together, these findings provide a scholarly basis for an interpretive 3D visualization of the landscape and settlement in Skien around the year 1000.
