Caesar's Camp is an Iron Age hill fort straddling the border of the counties of Surrey and Hampshire in southern England. The fort straddles the borough of Waverley in Surrey and the borough of Rushmoor and the district of Hart, both in Hampshire. Caesar's Camp is a Scheduled Ancient Monument with a list entry identification number of 1007895. It lies approximately 3 kilometres (1.9 mi) north of the town of Farnham, and a similar distance west of Aldershot. The hillfort lies entirely within the Bourley and Long Valley Site of Special Scientific Interest. Caesar's Camp is a multivallate hillfort, a fort with multiple defensive rings, occupying an irregular promontory, with an entrance on the south side. The site has been much disturbed by military activity, especially at the southeast corner. The remains of the hillfort are considered to be of national importance.
It is possible that Caesar's Camp developed in the Late Bronze Age, as a fort associated with the River Wey. There were three Iron Age phases of the fort. In its earliest form, Caesar's Camp was a univallate fort. In its second phase of development, the defences were multivallate with a timber palisade. Later, a bank was built over the line of the palisade, replacing it. After the third phase, the site was apparently abandoned until the medieval period, when a park pale was built, making use of the final phase of the Iron Age defences. Caesar's Camp belonged to the Farnham estate of the Bishop of Winchester in the 11th century; by the 13th century it formed part of a park associated with Farnham Castle.
