Arthog Standing Stones is a megalithic mound at Arthog, Gwynedd, in the United Kingdom. It is also known as Arthog Standing Stone. The monument is listed by Cadw under the number ME105, with grid reference SH652139.
The mound was made by using stones to support a cairn of earth and a burial place at its centre. Over time, the earth has disappeared, leaving a group of stones. Although they no longer form a complete circle, they may once have done so. The stones might also have been used for ceremonies or other practices.
The standing stones are dated to 4000 BCE to 800 BCE by typological estimate. No detailed information is given about the monument’s excavation, its original construction date, or any finds associated with it. The information about its appearance and possible uses is limited to what survives at the site.
Round barrows are among the commonest prehistoric monuments in Britain. Such monuments generally consist of a hemispherical mound of earth or stone raised over one or more burials, often surrounded by a ditch or bank. Most were built between about 2200 and 1100 BCE, from the Late Neolithic to the Late Bronze Age.

About this kind of monument
British barrows
Round barrows are among the commonest prehistoric monuments in Britain. A round barrow is a hemispherical mound of earth or stone raised over one or more burials, often ringed by a ditch or a bank. In Britain most were built between about 2200 and 1100 BCE, from the Late Neolithic to the Late Bronze Age. Antiquarians sorted them into bowl, bell, saucer and disc forms according to the shape of the mound and the ditch, and the types still appear on archaeological maps. Under the mound there may be a cist, a pit grave, or cremated bone in a pottery vessel; later graves were often cut into older mounds, sometimes thousands of years after the first burial.
Barrows are dated by radiocarbon dating, by pottery and by metalwork. The best-known group lies around Stonehenge. At Bush Barrow, about one kilometre south-west of the stones, William Cunnington opened the mound in 1808 and found a lozenge-shaped sheet of gold, a gold belt plate and three bronze daggers; it belongs to the early Bronze Age Wessex culture of about 1950 BCE, and the Normanton Down cemetery has some forty barrows along one ridge. Round barrows were also built, or reused, later: at Sutton Hoo in Suffolk, an Anglo-Saxon ship burial of the sixth to seventh centuries CE lay in a cemetery of mounds.
When visiting, look for the ring of the surrounding ditch, which is often easier to see in low light, for barrows sited on false crests and ridge lines, and for groups strung out along a ridge, as at Normanton Down.
