Until 1889 Grandpont was in Berkshire, although it was a tithing of the parish of St Aldate's, Oxford.
At some point between 1086 and 1094 Nigel was granted possession of two mills on the west side of Grandpont by Abbot Columbanus of Oxford, however by 1109 the mills were recorded as having been reconfirmed to the abbey.
Grandpont Bridge is a footbridge across the River Thames near the centre of Oxford, England.
