The landing of Lyra and the Gyptians at Trollesund is being filmed at Chatham Historic Dockyard in Kent this week. Film crews have been seen constructing a mock building front and “brownwashing” some of the existing buildings, with prop barrels and other dockside paraphenalia about. The dockyard, lieing on the banks of the River Medway, saw the foundation of the Royal Navy under Henry VIII.
