Description

The monument comprises the remains of a crannog, or lake dwelling, of prehistoric date.

The monument lies towards the E end of Loch Venachar close to the N shore. It comprises a crannog, or artificial islet, visible above water level as a mass of stones some 20m in diameter. Investigations in 1912 revealed the remains of waterlogged planks, some with mortice holes, among the loose stones on the surface of the mound, suggesting that water-logged organic remains relating to prehistoric settlement will be preserved within the body of the mound. There is no trace of a causeway to the shore.

The area to be scheduled encompasses the visible and submerged remains and an area around them in which traces of associated activity may be expected to survive. It is circular with a diameter of 60m as marked in red on the accompanying map, and includes a portion of the bed of the loch.
