Named after Waterloo Bridge, which commemorates the Battle of Waterloo.
The Strand Bridge Company's bridge was being built when Napoleon was defeated in 1815. It was meant to be called Strand Bridge, but the victory prompted calls for a 'Bridge of Waterloo', and it opened in 1817, two years to the day after the battle. The terminus opened in 1848 as Waterloo Bridge Station; it was officially renamed Waterloo in 1882, as people already called it.
