Knowe of Dishero

On the 1st 25” O.S. several slopes are shown. On it the site aligns NE/SW, with at the eastern side a rectilinear half (having a sub-rectangular pit [or perhaps stone] at right angles to the longer side half-way along), at the western side an arc of the same length, and at the northern side two arcs of almost similar sizes (the west one less curved) with a gap between them due north. The RCAHMS NMRS record no. HY41NW 6 describes a broch tower of internal diameter nearly 30’ having a 19’6” long section of inner wall-face visible on the west side to a height of some 4’6” with an opening of over 2’6” blocked up in modern times. Inside the east ditch it mentions faint traces of the outer broch wall. The rectilnear half makes me wonder if it hasn’t been re-used by the Vikings, like Castle Howe in Holm.
