Archaeology Notes

NS17NE 1 Centred on NS 17509 76383

(NS 1751 7637) Dunoon Castle (NR) (Remains of).

OS 6" map (1946)

Dunoon Castle, extant in the 12th century and allegedly so in the 6th, stood on a cone-shaped hill more than 80 feet high. It was a royal residence in the 14th century, and in the 17th century it fell into ruins.

It apparently consisted of three strong circular towers arranged in a triangle but only the foundations (14/15th century) of some of the pillars which supported the roof remain.

W Inglis 1895

Dunoon castle stands on a partly artificial motte.

E S Armitage 1912

The remains of Dunoon Castle are scant. The best preserved portion remaining is to the SW where there is a passageway 1.7m wide. The outer wall of this passage is 8.8m long and 1.6m thick, while the inner wall has a height of c.4.0m. The flat-topped mound on which the castle stood contains footings of wartime structures, and a modern geographical indicator.
