Kilmartin Glen (Nether Largie) is the densest concentration of prehistoric monuments in mainland Scotland, with more than 350 recorded sites within a six-mile radius of Kilmartin village in Argyll. The Nether Largie group is its central spine: the Nether Largie linear cemetery of five Bronze Age burial cairns laid out in a straight line over 1.5 kilometres, the Nether Largie Standing Stones with their lunar-aligned settings, and the Temple Wood double stone circle a short walk west. The cairns range from the early Bronze Age Nether Largie South (c. 3000 BCE, originally a Neolithic chambered tomb) to Nether Largie Mid and Nether Largie North, the last with carved axe-heads on its capstone. The standing stones were studied by Alexander Thom, who proposed they encoded the major southern lunar standstill; the alignment is still disputed but observable.
Kilmartin's monuments were placed within sight of one another deliberately, and most still are.
