Stone trough at Carl Wark hill fort, Derbyshire

Originally posted for the Guesswhere UK group.

This trough carved out of a single gritstone boulder is just outside the perimeter rampart of Carl Wark at Burbage, in the Peak District National Park, near Sheffield. Carl Wark is a spectacular, though somewhat enigmatic, hill fort - probably Iron-age, but with some later Roman usage.

The stone trough is even more enigmatic. No-one really knows what it is, or its exact age. Some would like to think it is an Iron-age bath, but it is more likely to be more recent, possibly a horse trough in use during the time of millstone manufacture, of which there is much evidence around and about.
