The loch is a natural feature, sitting in a hollow to the west of Walls Hill and close to the old North Castlewalls Farm.

[3] In 1960 a flint barbed and tanged arrowhead was found on the shore of Walls Loch,[4] a type typical of the Bronze Age ‘Beaker People’ and the introduction of metal working to the British Isles.

[7] Each phase of occupation would have impacted on the loch as a source of water for humans and domestic animals, fish etc as food, rushes and reeds for household use, etc.

[8] Whittliemuir pollen diagrams from the Iron Age show that a basic economy based on mixed farming existed in the area around the loch.

[9] The 19th century OS maps indicate a small oblong enclosure below Walls Hill on the west bank of the loch that contained trees.
