(NN 3222 4428) Tower (NR) (remains of)

OS 6" map (1970)

Achallader Castle, a small tower house, was built by Sir Duncan Campbell shortly before 1600. The castle was attacked and burnt by members of the Jacobite army in 1689, and is now fragmentary. While the N and E walls stand almost to their original heights, only a small portion of the W surives and the S wall has disappeared completely.

The tower is oblong on plan, measuring 8.7m from E to W by 6.7m transversely over walls which vary in thickness from 0.91 to 1.07m. The accommodation comprised three storeys and a garret, the side-walls rising to a height of 9.3m. The masonry is of random rubble laid in lime mortar, with dressings of schist.
