Created by William the Conqueror in the late 11th century, the rape of Bramber was separated out of the neighbouring rapes of Arundel and Lewes and entrusted to one of his knights, William de Braose, 1st Lord of Bramber.It was inserted so William de Braose could defend the Adur estuary, and a re-allocation of land to existing rapal owners became necessary.[4] The rape of Bramber is a strip of territory running northwards from the coast to the border with Surrey in the north.It contains a variety of different landscape areas – coastal plain and the mouth of the river Adur in the south, the South Downs and the Weald north of that, including the westernmost part of the dense Forest Ridge, known in the rape of Bramber as St Leonard's Forest.Ifield was the parish in the far north-east of Bramber rape, and in its own north-east corner on Lowfield Heath grew the County Oak, which traditionally marked the Sussex–Surrey boundary, as well as the boundary between the rapes of Bramber and Lewes.
