The remains of a small stone circle and a stone row can be found on the summit.

The remains consist of a degraded but still visible stone row.

Approximately five double stone rows and one single stone row are to be seen.

The stone row was first noted by historian Richard Carew in 1605.

The stone rows radiate from the circles in a roughly north-east direction.

It includes a stone circle and a stone row.

To test this idea he surveyed hundreds of stone rows and circles.

The stone row photographed faces the southernmost setting point of the Moon.

Topography of the stone rows (their location in landscape) is very variable and has no clear strong pattern.

Three stone rows she passed, then four more, each with the stones closer together, so that the seventh brought them touching to form a wall.
