Caesars Camp

Hob Uid: 407826
Location :
Greater London Authority
Bromley
Grid Ref : TQ4210064000
Summary : Earthwork remains of an Iron age hillfort, first recorded in 1790, now partly destroyed by landscaping for Holwood House. Excavations in the late 1950s confirmed the assumed Iron Age date. More recent excavations near the hillfort uncovered a ditch terminal which has been suggested to form part of a substantial ditched enclosure, although the information published to date makes any further comment impossible. Part of the hillfort was surveyed by RCHME in 1997.
More information : (TQ 421640) Caesar's Camp (NR). (1)

Caesar's Camp, or Holwood Camp, this hillfort originally enclosed
43 acres, as shown on Thomas Milne's plan of 1790 (2), but today
only parts of the W and N sides remain the N and E sides having
been destroyed by landscape gardening for William Pitt the
Younger who lived in Holwood House. The S side had been levelled a
century earlier. On the W side the massive ramparts are closely-
set; the two banks and ditches cover about 120 ft. and in some
parts there is a counterscarp bank. The ditch is 14 ft.9 in. deep
and 29 ft.wide. The rampart today stands more than 9 ft. above the
original ground surface. The inner fortifications were excavated
in 1956 and 1957. Three stages in construction of the rampart
were discovered each adding greater strength. The principal
entrance was on the western side; the inturn was exaggerated by
the siting of the gateway in a small natural valley which runs
into the interior of the fort. Other breaks shown in Milne's
plan are probably not original.

All the pottery is of Iron Age B type, Belgic pottery being
entirely absent. (2-4)

Survey of 1961 checked, and correct. (5)

Brief discussion of earthworks plus diagram of main entrance. (6)

Resue excavations before and during office construction in Holwood Park close to the hillfort resulting in the discovery of ditch c. 5m wide and 3m deep. The fill included a few sherds of pottery dated to the late Iron Age. It appears the ditch terminal was excavated. No further details appear to have been published. It is suggested that the excavated feature formed part of substantial ditched enclosure probably covering several acres. In the absence of any further information, including the NGR, it is not possible to comment further on this suggestion. (7-8)

In July 1997, the RCHME carried out a topographic survey in the south-eastern part of the fortification, at centre TQ 4235 6365, an area of around 2 hectares spanning the presumed line of the levelled ramparts. Three very low earthwork scarps and banks on parallel alignments are possibly the remains of the defences along the natural scarp edge but geophysical survey in the same area, by Geophysical Surveys of Bradford, revealed no supporting evidence. A full report and survey plan at 1:1000 scale, plus a copy of the geophysical survey report, are contained in the archive. (9)
