A coloured plan or bird's eye view of Dover Harbour and Town, shewing Lord Cobham's plan for a second sluice to the pent
Cartographer: Thomas Digges
Medium: Ink and pigments on vellum
The origin and purpose of this drawing are unknown. It shows Dover harbour in a pictorial style. Although engineering plans were often drawn to scale at this date, old style pictorial plats were still drawn. The drawing is undated but it is likely that it dates from the spring of 1583 . The two curved structures by the harbour mouth are the groins constructed over the winter of 1582-3 by Ferdinando Poyntz, whose experience of harbour works was gathered in the Low Countries.
It is possible that the cartographer was Thomas Digges who was the mathematician and engineer in charge of the scheme at Dover Harbour in the 1580’s, taking over from John Thompson.
