Flounder's Folly is a Grade 2 listed stone tower, standing on the skyline at the top of Callow Hill, a few miles north of Craven Arms, Shropshire.

The folly was built in 1838 by Benjamin
Flounder, a C19 industrialist, ship owner and public benefactor.
Photographs dating from 1938 show the tower fairly intact, and the text indicates that the battlements had been substantially rebuilt. A further collapse of the battlements occurred in the 1980's, suggesting an intrinsic weakness in the parapet design.
The parapets have been restored using Forest of Dean sandstone, and a new reinforced
concrete roof deck has been designed to
provide stability to the overhanging
battlements. A new staircase and
door have been inserted, and the
existing masonry walls
have been repaired
and repointed.
