There is a minefield control tower at Gallanach overlooking the Sound of Kerrera; it lies on the hillside on the south side of a caravan park.
This is an unusual building with only one other example still extant at Burnham on Crouch in Essex.
The building is a circular concrete structure with three stories. The bottom floor has two level loopholes and internally resembles a pillbox with two small rooms in the centre. There is a ladder up to the next floor which also has loopholes. There is a roof dome above with observation slits which is reached by a second ladder up to a steel landing, most of which has fallen away.
Externally the building is in good condition although internally it is covered in graffiti, presumably from residents of the adjacent caravan park.
There is a small rectangular brick building in the bushes alongside. This building is empty.
