Sulgrave is a village and civil parish in South Northamptonshire, England, about 5 miles (8 km) north of Brackley. The village is just south of a stream that rises in the parish and flows east to join the River Tove, a tributary of the Great Ouse.
Just over 1 mile (1.6 km) north of the village is Barrow Hill, a bowl barrow beside Banbury Lane between Culworth and Weston. The barrow is oval, about 130 feet (40 m) long, 80 feet (24 m) wide and up to 6 1⁄2 feet (2 m) high. It is Bronze Age and may date from between 2400 and 1500 BC. It may have been surrounded by a ditch, but this can no longer be traced. The mound may have been re-used in the Middle Ages as the base for a windmill. The barrow is largely intact, although it has been partly disturbed by badgers. It is a scheduled monument.
Castle Hill, at the west end of the village southwest of the church, is the earthwork remains of a Saxon and Norman ringwork castle. The northern part of the ringwork was excavated in 1960 and 1976.
