This fine ring is now enclosed within an overgrown wall and is overgrown with bracken in summer. Unusually it stands on low ground on moorland at 120 m O.D., 1 mile N of St. Buryan. It has been restored.
Once of about 20 stones, 1 quartz, the rest granite, in a ring 82 ft 7 ins x 73 ft 2 ins (25.3 x 22.3 m) across. The 2.5 m high 'central' pillar now leans considerably to the NE because of digging at its base by treasure- seekers. The circle stones have their smoother faces inwards like those of Boskednan (SI/11).
380 and 630 m NE are two tall stones, the top of the nearer being visible from the ring.
In 1864 a trench was dug across the interior of the ring but there were no finds.
William Stukeley believed this ring to be the first structure built by a group of immigrant Druids. Even more improbably Boscawen-Un is regarded by ley-liners fas the nucleus of a greater megalithic structure extending across the whole southern area of the Lands End peninsula1.
Boscawen-Un probably belongs to the Early Bronze Age, 1800-1500 be (c. 2230-1835 BC).
