Warren Farm, on Dinas Dinelle, is a substantial building set within a rectangular enclosure, which includes 3 large barns. The farm is shown on the Ordnance Survey County Series 1st edition 1889 map (Caernarvonshire XV 10 sheet) and is likely to be associated with the rabbit warren, immediately west of the farm. Dinas Dinelle Marshes were enclosed by an Act of Parliment and amounted to some 1500 acres. To the north of Warren Farm is Fort Belan (NPRN: 26459) and Y Foryd Nature reserve. Warren Farm is in current use as a holiday centre.
