A collapsed farmyard roof revealed an underground Iron Age chamber lined with stone pillars and alcoves. Rennibister Earth House is a souterrain (an underground stone-lined passage), an underground or partly underground structure, on Orkney Mainland.
Its discovery was sudden and unsettling. When a threshing machine broke through the roof in 1926, excavation uncovered disarticulated human remains from adults and children, turning a hidden earth house into evidence for later Iron Age treatment of the dead and the wider Bay of Firth settlement landscape.
What follows is drawn from published sources, with each claim labelled by how firmly it is established.
History
Rennibister Earth House was discovered on 12 November 1926 when a threshing machine caused the roof to collapse. The monument is an Iron Age underground structure known as a souterrain. Excavation uncovered the skeletal remains of six adults and twelve children.
The remains probably belonged to two or three family groups. The chamber has a corbelled roof, built with overlapping stones, supported by four stone pillars. The walls are lined with five small alcoves.
Nearby sites include Wideford Hill chambered cairn, Cuween Hill Chambered Cairn, and Grain Earth House. Historic Environment Scotland established the site as a scheduled monument in 1928.
