17th-century 'sham' built on an old Norman motte and bailey site (the Peveril family); the keep tower is a marvellous folly for the Earl to play King Arthur in; there is also an indoor riding rink that is unique in England; this place is out off the beaten track, though near the M1 motorway, but I'll give it the HIGHEST recommendation (right up there with Richmond, Tower of London, Dover, etc.); every room in the keep has a sit-in fireplace.
