that the Mackays may have built their castle on the site in the 14th century, on top of an existing old Norse fort.
The walls are generally 1.4 metres (5 ft) thick, or thicker, and have been built from roughly squared blocks of metamorphosed sandstone rock of varying thickness, laid in rough courses of random depth.
The upper floor entrance was on the south side and would most likely have been accessed by a ladder or removable stair.
There was a window in the east wall and a fireplace in the west, but both have now collapsed past recognition.
[3] The castle was updated in 2017 to make it more accessible with a galvanised steel spiral staircase and viewing platform inside allowing visitors a higher viewpoint over the Kyle of Tongue.
