Benjamin Flounders, a Yorkshire Quaker who had inherited a local estate, built this slim stone tower on Callow Hill in 1838 — reputedly to mark where four estates met, and perhaps to salute his own seventieth year. About 24 metres tall at the western end of Wenlock Edge, it fell derelict and lost its castellated top in 1987, before a local trust restored it and fitted a new internal stair in 2005. Now opened on advertised days for a four-county view; the footpath to it is free. Craven Arms station is about 2km away.
