(ND 0547 6358) Knock Glass (NAT) Broch (NR)

OS 1:10,000 map, (1975)

Knock Glass (name verified) is the turf-covered remains of a broch with outworks. It comprises the broch mound itself, 18.5m in diameter and 2.0m high surrounded by a berm and outer scarp, the latter showing signs of walling. On the SE side of the broch are two parallels, curving stretches of wall face of slabs exposed to one course high; they are 2.3m apart and 1.6m and 2.2m long and are interpreted as respectively the outer face of the broch and the inner face of the mural gallery at first floor level.
