Broughton Castle is a medieval fortified manor house in the village of Broughton, which is about two miles south-west of Banbury in Oxfordshire, England, on the B4035 road (grid reference SP418382). It is the home of the Fiennes (in full Twisleton-Wykeham-Fiennes) family, Barons Saye and Sele. The castle sits on an artificial island in pastureland and is surrounded by a wide moat. Across the small bridge lies the parish church of St Mary the Virgin, surrounded by its historic cemetery. A Grade I listed building, it opens to the public during the summer.
