The walls and roof of the boathouse are wrought from cut timber, but underfoot the Norse walk on sand or rock.
The medieval period in Scandinavia and the Viking colonies saw the propagation of a form of building intimately linked with maritime culture: the naust. These buildings were primarily used to shelter vessels and occasionally their crew, especially in winter when sailing became impossible. Built slightly above sea level, they came in various shapes and sizes—between 4 and 40 m long and up to 10 m wide—depending on the vessel being sheltered. The walls and roof were made of wood with piled rock foundations, and the ground was dug out to make room for the keel. Like the ship it contained, the naust could increase its owner’s prestige, and according to sources some were even used to hold royal banquets.
