Lanyon Quoit is a dolmen in Cornwall, England, United Kingdom, 2 miles southeast of Morvah.

[5] Nine years later enough money was raised by local inhabitants to re-erect the structure, under the guidance of Captain Giddy of the Royal Navy.

One of the original stones was considered too badly damaged to put back in place, thus there are only three uprights today and the structure does not stand so high as it once did.

[3] In 1769 William Borlase described the megalithic site for the first time in a publication, illustrated with etchings in which the Lanyon Quoit's design and floor plan has a different look from today, given changes made following its 1815 collapse.

[11] He reproduced the etchings of his ancestor and found them much more valuable than any other contemporary sketch since the monument had been subjected to such considerable change.
