Away from the valleys, permanent farms started to appear in the 17th century one the Anglo-Scottish troubles had come to an end. There are still buildings on some of these 17th century sites, but none of them date to that period. Some of them are still complete structures but very few are farms; many have been repurposed as outdoor centres (such as Milkhope in Northumberland) – or even holiday homes. Others are either in a state of ruin (Buckham’s Walls and Seefew), or else have disappeared completely (such as Dryhope). In one or two cases this happened before the first Ordnance Survey maps of the area were published, and the precise position of the farmhouse is unknown.
