Achavanich Standing Stones

On a low rise above the southern tip of Loch Stemster, in the open Caithness countryside near Latheron, stands one of northern Scotland's strangest prehistoric monuments. Achavanich is not a stone circle at all, but a vast horseshoe of upright slabs arranged in the shape of an elongated letter U. It is this unusual layout, and the way the stones face inwards rather than side-on, that makes the site a genuine rarity and a magnet for anyone drawn to ancient ritual landscapes. Around forty centuries ago, builders quarried the local Caithness flagstone straight from the bedrock and stood some fifty to sixty stones here; about thirty-six still survive, the tallest reaching roughly two metres. The setting measures some seventy metres long and thirty across, open at one end, and looks out toward hills that may have served as markers for the sun and moon. Right beside the monument lies the grave of 'Ava', a young Bronze Age woman whose rediscovered burial became one of the most intensively studied prehistoric finds in Britain.
