Full Description

The mound containing remains of broch measures approx 35m N-S by 21m transversely and 0.9m high. It extended W into adjacent field, but has been ploughed out.
Surveyed at 1:2500. Visited by OS (J M) 28 April 1982.

All that remains of this feature is low grassy mound of indeterminate diameter, situated in pasture field. It is now almost ploughed out but scatter of stones still remains on and around mound. According to Mr Gunn (Brabster, Canisbay), an excavation was carried out about 50 years ago, revealing sections of a circular wall and many limpet shells. The artifacts found during excavation by Mr Nicholson, now deceased, and given to Mr Sinclair, also deceased, are now either in possession of Mr Nicholson's grandson at Nybster or with Mr Sinclair's niece at Dunblane.
Revised at 1:2500. Visited by OS (R B) 25 February 1965.

This mound, under cultivation, contains remains of broch whose dimensions are unobtainable. The mound was partially excavated by John Nicholson, Nybster, and from it were recovered a rotary quern, three water-worn stones, probably loom-weights, and a diminutive cup or hollowed pebble, 2.75 by 2 by 0.75ins. With the exception of one of loom weights, which is in NMAS, donated by Alexander Sinclair in 1911, objects are in possession of Mr Sinclair.

This probable broch in Canisbay, Caithness, was partially explored by John Nicholson of Nybster some time before 1910 at which time parts of a circular wall were uncovered [1]. Nothing is visible now except a low, grassy mound.
Finds included a stone rotary quern, 3 grooved pebbles some 15cm (6in) long –possibly loom weights – and a small stone cup only 7cm (2.75in) long. One of the “loom weights” is in the National Museum [3].
