Blackhammer Chambered Cairn

The Blackhammer Chambered Cairn, located on the island of Rousay in Orkney, Scotland, is a 4000-year-old Neolithic tomb, known as an Orkney–Cromarty chambered cairn, characterized by stalled burial compartments. The tomb, first excavated in 1936, originally consisted of seven compartments divided by pairs of standing slabs, with four of these slabs missing at the time of excavation. The remains of two adult males, a pottery bowl, a flint knife, a polished stone axe, and animal bones were found during excavation. The tomb's decorative masonry, set in a triangular design, is a characteristic trait of Neolithic tombs on the island of Rousay.
