Spend a day in Greenwich, a Thameside village on London's eastern outskirts by which the world sets it clocks, with a rich maritime history, stellar little museums, and the Prime Meridian
Set your watch by the actual Greenwich Mean Time clock, straddle the Prime Meridian line that divides the eastern and western hemispheres, and tour the fascinating little museum about it all
See the coat in which Nelson was shot, bullet hole and all, along with some fantastically beautiful old astrolabes and an indescribably cool interactive display on the Battle of Trafalgar

Nelson's body lay in state in in Thornhill's impressive Painted Hall of this vast Christopher Wren building in Greenwich
Harrods of London installed a novelty in 1898: the world's first true escalator (to be fair, an inclined moving belt with metal bars for traction did make its debut two years earlier on Coney Island).
