Nether Largie Standing Stones, Kilmartin Glen

A group of five standing stones southeast of Temple Wood Stone Circle in Kilmartin Glen, arranged on a northeast-to-southwest axis with two pairs flanking a central menhir. The tallest stones reach up to 2.85 m, and the central stone bears 23 cup marks, three with surrounding ring marks. Constructed around 3,200 years ago, the cup carvings may be 1,500 years older, suggesting reuse of ancient carved stones. Alexander Thom proposed the alignment served as a lunar observatory for predicting eclipses, calling it one of the most important megalithic sites in Britain.
