Archaeological recording by T Howe of SCC and A Norris of SyAS during drainage ditch clearance works. Two sections across a former watercourse shown on a 1701 estate map of Albury Park as ‘Henry Howards Watercourse’ were examined. The watercourse appears to have been constructed as part of the extensive water management improvements in the area, undertaken by Howard (later the 6th Duke of Norfolk) and diarist John Evelyn in the late 17th century. No evidence for the original date of the feature was found.
