Monument record MHG9653 - Broch, Upper Bighouse

This broch, mutilated and turf-covered, measures about 10m in diameter inside a wall about 4.5m thick. From the debris-filled interior wall stands to a maximum height of 1.5m; there are breaks in the wall in the east and west arcs, but neither can be positively identified as an entrance. An outer face of base stones is intermittently visible round the east. The broch is situated on a moraine ridge and protected by two lines of defensive outworks. The first comprises cuttings through ridge in N & S, isolating broch position but for a narrow neck across approach on N side. Inside this is an earth and stone rampart pierced by an entrance from NW and apparently merging with natural slope on E. A noteworthy feature is the boulder slab revetting on N of the entrance. Outside the broch on NE are the footings of later or late structure(s).
