Lying in the shadow of the Knockmealdown Mountains, Castle Grace, County Tipperary is believed to have been built by the de Bermingham family around the mid-13th century. Its substantial square keep originally had a tower at each corner but only two circular ones remain. The castle’s ruins now serve as a walled garden for an adjacent Georgian house, the upper sections of stone and brick interior at present smothered in cascades of wisteria.
