Tucked into one of the few remaining slips that enabled ships to unload in Southwark (another is Hay’s Galleria, downstream by the HMS Belfast, now a boutique shopping area), is a 1:1 replica of Sir Francis Drake’s square-rigged Tudor galleon, which circumnavigated the world from 1577 to 1580. This 1973 version, which is so tiny you will forever feel pity for those old explorers, made its own circumnavigation in 1980. It was recently wrested from the trust that once owned it, and the new owners are trying to put its maintenance back on even keel, as it were. For now, tours are self-guided, but on weekends there may be guided ones if you check the schedule ahead of time.
