Remains of an Iron Age house cluster north of Brønnøysund, Nordland, north Norway

The eight remaining, oval to rectangular houses (six are visible, mound-like structures) were shown by gradiometer mapping to have an assumed stone foundation wall and two or three axially-located hearths. Outside this presumably horseshoe-shaped cluster of houses (partly destroyed by a main road) are eight visible cooking mounds composed of fire-cracked stones and charcoal. The mapping revealed several small cooking pits and diffuse burnt patches in the north, east and west (on both sides of the main road), as well as larger, overgrown occurrences of fire-cracked stones and charcoal in the south, perhaps marking totally flattened cooking mounds. In the centre of the horseshoe, the mapping identified an area of enhanced positive anomalies thought to represent a communal building or open-air site with a central hearth or fire.†
