Deptford, Greenwich and Erith were important docks on the River Thames.
Deptford is located on the south bank of the Thames, on the eastern edge of London. Greenwich is immediately east of Deptford. Erith is eight miles further east. All three docks were established by Henry VIII, but Deptford – site of the first Royal Dockyard – was undoubtedly of greatest importance: for much of the period during which Britain ruled the waves, her ships were built there.
