Stroanfreggan Cairn is a large circular cairn, measuring 73 feet (22.2 metres) across and up to 5.2 feet (1.6 metres) high on one side. It is just a small part of the size that it once was, having been used as a quarry. Upon investigation in 1910, a cist was uncovered, a small, coffin-like box. It contained a flint knife and some bone fragments, now removed for preservation. Some bronze, flints and charcoal were also found at this site and are now housed at Dumfries Museum.
