A global capital carrying 2,000 years of layered history — from the Roman port of Londinium, through the Tudor Tower and Victorian streets, to the glass towers of the City. The world city for theatre, finance, and museums (the British Museum, the National Gallery, the Tates — all free). Brace yourself for long distances, ride the Tube, and split the plan by zone: Westminster, the City, South Bank, the East End. Prices are in pounds (£), and you tap for travel with an Oyster card or contactless.
