Also known as, or recorded in historical documents as; Cann Office Hotel

In the community of Banwy. In the historic county of Montgomeryshire (Modern authority of Powys, preserved county of Powys).

A mound, the SE half of which has been levelled, 4.0m high and perhaps originally 24m in diameter. "Bronze instruments" are said to have come from the levelled part of the mound. To the S an angle of scarping (at SJ01181067) may, if not a product of garden landscaping, indicate an enclosure c.54m by 46m. Three sides of a rectilinear enclosure, 47m by at least 35m, ditched at the E angle, defined elsewhere by scarps. Trenching in 1962 produced med. pottery. Very damaged by developement.
The business-like Cann Office name is actually derived from 'Cae'n y ffos', meaning fortified or ditched enclosure. (Laurence Main, 1989)

The Ordnance Survey Map Grid Reference is SJ01181073
