Blackhammer Chambered Cairn

The tomb, constructed around 3000 BC, is a Orkney–Cromarty chambered cairn, characterized by stalled burial compartments.

The monument is located near the base of a hillside on the island of Rousay, in Orkney, Scotland.

Above the tomb, near the top of the hill, and built during the same time period, is the Knowe of Yarso chambered cairn.

It was determined to have originally been constructed with seven compartments divided by pairs of standing slabs.

Skeletal remains of two adult males were uncovered during excavation, along with a pottery bowl, a flint knife, a polished stone axe and animal bones.
