A grassy knoll rises apart from the surrounding west-coast fields of Arran. Torr a’Chaisteal is an Iron Age dun, a compact fortified homestead, with turf-covered sandstone walling and traces of an outer work on the landward side.
The interior is modest, but the setting gives the place its strength. Antiquarian excavation in the 19th century found bones, shells, a quern stone and pieces of haematite iron, offering a small glimpse of activity inside and around the stronghold.
What follows is drawn from published sources, with each claim labelled by how firmly it is established.
History
Torr a'Chaisteal is an Iron Age fort or dun on the Isle of Arran. A dun is a compact fortified homestead, one of a wider class of later Iron Age defended sites in western Scotland. The monument stands on an isolated grassy knoll on Arran's west coast, north-east of Sliddery.
The turf-covered walls are formed from large sandstone boulders. A short stretch of wall lies east of the dun. A substantial earthwork on the landward approach may have formed an outer defence.
Nineteenth-century antiquarian excavation uncovered human and animal bones, shells, the top stone of a quern and pieces of haematite iron. The pack notes Kilpatrick Dun, farther north, as a useful Arran comparison.
What to look for
-
Isolated knoll

-

-
Outer earthwork
The landward approach preserves an earthwork that may have served as an additional defence.
-
Compact enclosed area
The defended interior is small, fitting the dun interpretation.
