Rogers' Tower

Rogers' Tower is a folly, likely used as a look-out tower, built in the 18th century. It is constructed of granite rubble with rubble dressings. The tower features a corbelled granite dome beneath a roof that is concealed by a parapet with pinnacles over the four corner turrets.

The plan is a square single cell with corner turrets, designed in a Gothic style. The southeast entrance front has a central pointed doorway with an outer ogee-headed order. Above the doorway is a blind polygonal 'quatrefoil'. On either side of the doorway are two identical turrets, each with shouldered-arched windows on the front and outer sides, and blind slits above. The rear turrets are blind.

Inside, the tower has a domed granite ceiling and provides access to each of the turrets, though there is no access to the roof. The tower is likely associated with John Rogers of Treassowe, who lived from 1750 to 1832. It is situated prominently on the hill of Castle an Dinas, creating the impression that both the tower and the hill are larger than they actually are.
