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.<ref>William Borlase: ''Antiquities Historical and Monumental of the County of Cornwall'', Bowyer and Nichols, London 1769</ref> Lanyon Quoit collapsed in a storm in 1815 and was re-erected in 1824.

An etching from 1857 by R. T. Pentreath shows the megaliths in their present arrangement.<ref>Richard Edmonds, (1862), ''The Land's End District and its Antiquities, Natural History, Natural Phenomena and Scenery'', Smith</ref> A similar drawing appears in the 1864 book ''A Week at the Land's End'' by [[John Thomas Blight]].<ref>John Thomas Blight, (1861), ''A Week at the Land's End'', Longman</ref>

In 1872, [[William Copeland Borlase|William Borlase]], a descendant of the earlier Borlase, conducted further investigations and excavations were carried out.<ref>William Copeland Borlase, (1872), ''Naenia Cornubiae'', Longmans</ref> 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.

In 1952, the then owner Edward Bolitho from Tregwainton donated the plot of land with the monument to the [[National Trust for Places of Historic Interest or Natural Beauty|National Trust]].
