Hamar was a bishop's seat from 1152, and its cathedral stood on a headland in Lake Mjosa until war and fire in the sixteenth century left it a ruin; what survives is a section of the nave arcade, four arches of grey stone on massive piers, which stood open to the weather for four hundred years. In 1998 a protective structure designed by Kjell Lund was completed over them: a glass and steel canopy fifty metres long enclosing the ruin entirely, so the arches stand in a lit, weatherproof volume that is used for concerts and weddings. The surrounding Domkirkeodden site includes the Hedmark Museum, with a building by Sverre Fehn inserted into a medieval fortified farm, and an open-air collection of historic buildings.
What you actually see
- The arcade ruins - four surviving arches of the medieval cathedral.
- The glass canopy - a fifty-metre protective structure enclosing them.
- The Fehn museum building - a modernist insertion into a medieval farm.
- The lakeside site - a headland in Mjosa with an open-air building collection.
When to go
May to September, when the whole site including the open-air museum is open; the glass hall hosts concerts and is closed to visitors during events. Winter opening is limited to certain days.
Honest expectations
The ruin itself is a fragment, four arches rather than a building, and the interest is as much the modern canopy as the medieval stone. Entry covers the whole museum site, which takes longer than the ruin alone. Events close the hall without much notice.
Nearby
Hamar town and Lake Mjosa are alongside; the Skibladner paddle steamer calls at the town quay.
