Apart from settlements associated with the forts, Roman Cumbria consisted of scattered rural settlements, situated where good agricultural ground was to be found in the Solway Plain, the West Coastal Plain, and in the valleys of the Eden, Petteril and Lune. Archaeological evidence for these sites is thin and is mostly based on aerial surveys of crop marks. There is a bias towards sites in more upland areas, since lowland sites have been subject to extensive ploughing or development. The major sites identified include the following. In the Solway Plain and southern Scotland area there are Holme Abbey, Fingland, Wolsty Hall, around Old Carlisle, along the Annan Valley, east and west of Dumfries, around Newton Stewart and Wigtown Bay, along the valley of the River Wampool, at Silloth Farm, and Risehow. Along the Eden and Petteril valleys we have Dobcross Hall, Stockdalewath, Clifton Dykes, Old Penrith, Brocavum, Kirkby Thore, Yanwath Woodhouse. In the upper valleys of the Eden and Lune are Long Marton, Murton, Dufton, Berrier Hill, Waitby, Crosby Garrett (near to which a fine Roman cavalry display helmet was discovered in 2010), Ravenstonedale, between Crosby Ravensworth and Sunbiggin, in the Kirkby Stephen area, Eller Beck. In the central Lakes there is Aughertree Fell.
