Historical places in Europe

These stone rings are prehistoric burial chambers from the late 3rd millenium BC. There are about fifty of those, so-called clava cairns, in this part of Scotland. Probably the most well known is the Balnuaran of Clava (picture) not far from Inverness. Here, you will find three chambers, two with chamber-passages and one without, each encircled by big standing stones - a bit like Stonehenge. Cremated bones have been found inside the chambers, but else not much is known about these mysterious Bronze Age cemeteries.
