Under threatening evenings skies Roseberry’s folly stands in a prominent position on an ironstone bedrock. A summer or prospect house, built sometime in the late 18th century. The fashion to “enhance the landscape” was prevalent at the time, although modest by Capability Brown’s designs, they may have had an influence. Another summerhouse is marked on old O.S. maps on Faceby Bank but that has long since disappeared. During the Napoleonic Wars it is thought the summerhouse was commandeered by the militia manning the beacon that would have been lit on Roseberry in the event of an invasion.
