The area spans 5,000 years with a multitude of cairns, standing stones, carved rock, stone circles, forts and castles. Kilmartin Glen is considered to have one of the most important concentrations of Neolithic and Bronze Age remains in Scotland.
There are more than 350 ancient monuments within a six mile radius of the village, with 150 of them being prehistoric. Monuments include standing stones, a henge monument, numerous cists, and a ‘linear cemetery’ comprising five burial cairns. Several of these, as well as many natural rocks, are decorated with cup and ring marks.
The remains of the fortress of the Scots at Dunadd, a royal centre of Dal Riata, are located to the south of the glen, on the edge of the Moine Mhòr or Great Moss.
