The museums are free, the parks are royal, and Black Britain's heartbeat — Brixton, Notting Hill, Windrush and all — gives the old empire its best music. Mind the gap.
London holds the empire's receipts — the museums are full of them, and they're free to inspect. The British Museum, the Tates, the V&A, the National Gallery: a world-class education in looted splendor and genuine wonder, no ticket required. Budget your feet accordingly.
But our London runs through Brixton. The Windrush generation landed there in 1948 and built Black Britain's capital — Electric Avenue's market energy, the Black Cultural Archives on Windrush Square, plantain and patties and sound-system heritage on every block. Notting Hill adds the Carnival story (Europe's biggest street party, born of resistance in 1959).
The city rewards wanderers: river walks from Westminster to the Tower, Sunday roasts that justify empires of their own, and a pub culture that turns strangers into a round.
Museum strategy, Brixton with the history attached, theatre tickets sorted, and the Sunday roast booked by Wednesday.
