Archaeologists have conducted several excavations in the inner city since the 1960s revealing wells, streets, homes and workshops.
In the buildings and adjoining archaeological layers, everyday utensils like combs, jewellery and basic multi-purpose tools from approximately the year 900 have been found.
In the 900s an earth rampart for the defence of the early city was constructed, encircling the settlement, much like the defence structures found at Viking ring fortresses elsewhere.
The city was founded on the northern shores of a fjord at a natural harbour and the primary driver of growth was for centuries seaborne trade in agricultural products.
