Stokesay Castle Roof.

Stokesay's magnificent open hearthed great hall displays a fine timber roof, shuttered gable windows and a precipitous staircase, its treads cut from whole tree-trunks. It is flanked by the north tower, with an original medieval tiled floor and remains of wall painting, and a 'solar' or private apartment block, and beyond this the tall south tower - the most castle-like part of the house, self-contained and reached by a defensible stairway.
