They average 100 to 200 feet in diameter, though a few are as large as the largest henges. The circle henge is a combination of both circle and henge and is less common. Henges lie to the East of Britain and Scotland and stone circles to the West, the two forms uniting in the middle of Southern Britain and Northern Scotland. Stonehenge, Wiltshire, is the best example of a circle henge. A cairn is a long or circular burial mound made from a mass of small stones.
CUPS are circular hollows carved out of the rock by a sharp stone or antler.
Cup and ring marks are often found close to burial mounds, but their purpose and meaning remains unknown.
