Carlingwark Loch contains several islets, on one of which is a crannog, or ancient lake dwelling.
The crannog of Lagore, the first discovered in Ireland, was examined and described by Sir William Wilde in 1840.
A crannog in Loch-an-Dhugael, Balinakill, Argyllshire, described by the same explorer in 1893, revealed a substructure similar to that at Lochlee, with a double row of piles enclosing an area 45 to 50 ft.
The crannog of Cloonfinlough in Connaught had a triple stockade of oak piles, connected by horizontal stretchers and enclosing an area 130 ft., in diameter, laid with trunks of oak trees.
In the crannog of Lagore, county Meath, there were about 150 cartloads of bones, chiefly of oxen, deer, sheep and swine, the refuse of the food of the occupants.
