The Broch of Borwick is at first sight the stump of a relatively well-preserved broch standing spectacularly at the tip of a precipitous promontory, but it has not only suffered at the hands of an antiquarian excavator, and the cliff-faces are steadily receding on the N and SW where the wall is collapsing into the abyss. The broch measures about 8.2m in diameter within a wall between 3.5m and 4.6m in thickness and still presents up to 2.4m of neatly coursed outer face to either side of its checked entrance on the SE, which also has a guard chamber. There was evidently a settlement outside the broch, but it is difficult to make any sense of the remains visible today, and nor of any other defences barring access on the landward side. Nevertheless, in the account of his excavations, in which he dug down through a mound over 6m high, William Watt describes an outer wall cutting off the promontory that was 1.8m thick at the base and tapered upwards to about 1m at a height of 2.7m. Confusingly he asserts that this wall was 'founded in the moat' (Watt 1882, 447) 15m to 18m broad that he believed also traversed the approaches to the promontory, of which little coherent trace can now be seen. The enclosed area was roughly triangular, measuring perhaps 50m from NE to SW immediately to the rear of the wall by at least 40m transversely (0.11ha).

Assemblage includes: two long- handled bone combs; one composite, single-edged round-backed comb, 1 single-edged non-composite comb, one broken double-edged composite comb; one small whale vertebra cup; a socketed handle; three needles; a spindle whorl; a cetacean ivory toggle and a possible antler bridle cheek-piece. Stone objects include: some thin, round stone discs, probably pot lids; a polished gaming piece; a possible stone lamp; a perforated whetstone; hammerstones; Skaill knives and choppers; and querns. An iron rod was found and a single sherd of pottey. Ongoing erosion has led to the recovery of more pottery and midden (Now in Tankerness Museum; Lynn and Bell 1983; 1987)
