[1] West Lanyon Quoit is located northwest of Penzance near the road between Madron and Morvah.

[3] West Lanyon Quoit was originally covered by a large barrow mound.

[5] When the servants had removed "near a hundred cart-loads" they discovered "the supporters of a cromlech, from which the coverstone was slipped off on the fourth side, but still leaning against them.

[5] Digging into the chamber led to the discovery of a broken urn, ashes, and some human bones.

[5] Given that the chamber was full of mound material, it is now thought that the tomb had been opened previously and that the urn and bones were a secondary, probably Bronze Age, cremation burial.
