Renhold Ring is an earth and timber ringwork and bailey fortress, partly encased by a wide wet ditch. To the west of the ringwork, a possible large bailey is encased, by the faint remains of a rampart and ditch. Occupying a spur, the large circular mutilated ringwork is encased by high ramparts, with the original entrance probably on the west. In the early 19th century undated inhumations were found near the surface, when the castle was regarded as a Roman amphitheatre. The site has a dense cover of trees, so it is best viewed in winter. 4 miles west is Bedford Castle and a mile north is The Creakers.
