The tower at 'Cas Torrogy' is recorded as being newly built in 1307. The surviving remains consist of a rectangular platform, measuring about 42m north to south by 27m, set on low ground close by a stream on the north. It is defined by ruinous walls and a moat, about 15m wide on the west and 10m across on the north. On the south front two towers, of indeterminate form, project to extend the frontage to 64m.
