The proposal to build a replica seventeenth century ship in Deptford sounded like a fantasy when people first started floating it, but it now seems to be gaining some momentum. The would-be developers of the Convoys Wharf site on the riverfront have come under pressure to acknowledge the site's history as the location of the Royal Dockyard, and seem to be coming round to allowing space for the project in their plans. Further details at Build the Lenox.
The original Lenox was a Restoration warship built at Deptford and launched in 1678.
