The village is about 130 metres above sea level in the Chiltern Hills. The remains of a Roman farmhouse were found during an excavation of the Common in 1955, as well as later Saxon remains. These were not considered to be worth retaining in an exposed condition and so the area was re-covered. There were originally two villages: Bix Brand and Bix Gibwyn. The toponym has at various times been Byxe and Bixa. The Domesday Book of 1086 records Bixa as part of the Hundred of Binfield.
