Steinacleit is a possible chambered cairn although more recent analysis suggests it may in fact be the remains of an old building.

When the remains were first uncovered in the 1920s they were interpreted as a robbed chambered cairn with at least thirteen kerb stones situated within a large oval enclosure around which was a stone wall of varying width. This stone wall has also been interpreted by some as the remains of a stone circle.

Re-analysis in the 1970s postulated that the stones could actually represent a ruined building of a previously unknown type, the kerb stones in particular being an unusual feature, surrounded by a field wall.
