"Barrows are the most numerous of the various prehistoric funerary monuments (the main period of round barrow construction occurred in the Early Bronze Age between about 2200-1500 BC (a period when cremation succeeded inhumation as the primary burial rite), although Neolithic examples are known from as early as 3000 BC. In general round barrows comprise a rounded earthen mound or stone cairn, the earthen examples usually having a surrounding ditch and occasionally an outer bank. The majority of the estimated 30,000 round barrows from this period are bowl barrows. Bell, disc and pond barrows are considerably rarer.

The probable barrow remains are located approximately 260m to the south-east of Westenhanger Castle (NHLE 1020761) and form part of wider funerary landscape, being in the vicinity of the earthwork and buried remains of several other barrows to the west of this site. The remains are within an area of land historically part of the former deer park to Westenhanger Castle, and which in the late-C19 became part of the Folkestone Racecourse. The feature is adjacent to the north-west corner of a late-C20 lake constructed in the centre of the racecourse.

A curvilinear anomaly was first identified through geophysical survey (2020) as the remains of a ditch to a round barrow, or evidence of activity relating to Westenhanger Castle. Subsequent trial trenching
(2020) confirmed the sections of a curvilinear ditch.The artefactual evidence and charcoal deposits
indicate that the feature is likely to be a ring or pennanular ditch to a former barrow monument, possibly of Early Bronze Age date. In recent archaeological investigations this is documented as barrow 253.

Details

PRINCIPAL ELEMENTS: the probable buried remains of a barrow dating to the early Bronze Age.
DESCRIPTION: the probable remains of a barrow, surviving as a buried curvilinear ditch appearing as an incomplete circular anomaly on recent geophysical surveys. Trial trenching of two sections of this
feature has identified two curvilinear ditch segments representing a ditch at least 5m in diameter, and 0.4m deep and 0.16m deep respectively. Finds include charcoal inclusions, burnt flint, a small pottery
assemblage probably dated to the Bronze Age or Early Iron Age, along with a small amount of worked
flint and fired clay. There was no evidence of a bank or a central mound remaining."
