The Sna Broch has been reduced to no more than an arc of ramparts and ditches at the top of a beach. Sited on soft till deposits rather than the typical precipitous locations more usually adopted by promontory forts, there is now insufficient evidence to demonstrate whether these were simply the outworks of a broch or whether they incorporate elements of a promontory enclosure, the rocks lying some 70m offshore perhaps indicating its possible extent. Nevertheless, the arc includes the remains of at two ditches with external ramparts and it is likely that there was also a third rampart within the inner ditch rather than simply the wall of the broch (RCAHMS 1946, 55-6, no.1210, fig 542; MacKie 2002, 119); recent fieldwork along the shore has observed evidence of waterlogged deposits beneath rubble in the inner ditch. On the S the outermost rampart returns to meet the middle rampart, a configuration that possibly indicates that this was the site of an entrance, though the RCAHMS investigators attribute it to access to a well noted by earlier visitors in one of the ditches (Low 1879, 166; Hibbert 1822, 387). The RCAHMS plan drawn up in 1930 identifies a gap in the outer rampart at the N end of the arc as the remains of an entrance. Pottery and hammerstones have been recovered from the eroding section, including material from beneath one of the ramparts (Fojut 1983, 21).

Possibly the site of a broch, but this has been destroyed by erosion before the 19th century
Supposed to have been a well in one of the ditches, but this must represent later usage
