Dry Hill Camp is a large enclosure of probable Iron Age date looking across the Eden/Medway Valley to the northern part of the Low Weald and North Downs. It is multi-vallate and lies just within Surrey, close to both Kent and Mid-Sussex. An excavation in 1932 recovered few finds and the site remained enigmatic. From 2011-2013 a level 3 tape and compass survey to check the condition of the earthworks was undertaken and a report is now available in the pdf attached below.
In 2014 land on Gravelly Hill was purchased by Caterham School and they expressed an interest in knowing the archaeological and historical background to their new land. The late Peter Gray had already noted the presence of earthworks within the area but access had previously been limited. As a result of the change of ownership members of the Surrey Archaeological Society undertook aa measured survey of the land within the medieval park and a small area to its immediate north.
