Forget Big Ben or the London Eye, the real sights of this city are underground – and we don't mean on the tube. The London Transport Museum is putting on another round of its hugely popular Hidden London tours, where you'll be able to nose around a deep-level World War II shelter in Clapham and the disused Down Street station where Prime Minister Winston Churchill held cabinet war meetings and took refuge during the Blitz.
They've also added two new locations, including the tunnels below Euston station and London’s first skyscraper at St. James’s Park, if you fancy coming up for air. Tickets go on sale on April 20, but if you're really keen, you can bag yourself priority booking by signing up to the London Transport Museum newsletter by 11.59pm on April 18.
Tour start on May 7. Book tickets here.
