Summary

There is a long-standing tradition that Sumburgh Head is the site of a fortification of some description, though the assertion by Sir Henry Dryden that it was a broch (1874, 211) is otherwise unsupported by any evidence. Nevertheless, George Low, visiting in 1774, claimed that access across the neck of the promontory was barred by 'a ditch and strong wall' (1879, 185), and in 1968 the OS identified two possible ramparts and ditches spanning the 50m wide neck where the road to the lighthouse zigzags up towards the summit; the ramparts, which are plainly visible on satellite imagery taken in 2004, have been reduced to scarps between 0.5m and 0.8m in height. This implies a large fort some 300m in length enclosing about 1.9ha along its crest, though the area of broken outcrops and bare rock descending to the sea covers a considerably larger area. Inevitably these possible defences are set at the point where any later agricultural boundary enclosing the headland is likely to have been placed and the true character of these remains can only be established by excavation. No trace of any entrance is visible at the neck, and nothing of the 'foundation of a large house' that Low observed at what he considered to be the entrance, nor of the numerous small buildings that lay 'along the wall and at some distance' (1789, 185), features that Raymond Lamb has suggested might have been comparable to the structures found in several promontory enclosures that are likely to have served as early medieval monastic sites (1973, 78).

Investigation History

Sumburgh Head has been photographed by RCAHMS Aerial Survey Programme, though there is little evidence of any fortifications on the photographs

Investigations:
1st Identified Map Depiction (1654):   Annotated 'The ancient fort of Swenbrugh' on Orcadum et Shetlandiae Insularum accuratissima descriptio, in Blaeu's Atlas
1st Identified Written Reference (1774):   Description by G Low (1879, 185)
Other (1930):   Description (RCAHMS 1946, iii, 45, no.1189)
Other (1968):   Possible ramparts surveyed at 1:2500 by the OS
Other (1970):   A visit by Raymond Lamb is confirmed by a single photograph held by RCAHMS, though he does not offer his own observation of the defences recorded by the OS (Lamb 1980, 81-2)

Interior Features

Occupied by the lighthouse and its facilities and services. According to Low a series of small buildings were visible adjacent to the defences
