London holds more free world-class collections than any city on earth, from Tate Modern's turbine hall to a Georgian architect's house left exactly as he died in 1837. Three days of galleries, playhouses and studio streets, walked in tight clusters.
Giles Gilbert Scott's 1947 oil-fired power station, converted by Herzog & de Meuron in 2000. Free permanent collection across Boiler House and Blavatnik levels — Rothko's Seagram Murals, Bourgeois, Hockney. Open 10:00–18:00 daily; paid exhibitions from £18.
Christopher Wren's 1710 masterpiece, the fifth cathedral on this ground. 528 steps climb through the Whispering Gallery to the Golden Gallery at 85m. Adult ticket £26 online, £28 on the door; open Mon–Sat 08:30–16:30, closed Sundays to visitors.
The architect's own house, preserved by Act of Parliament exactly as he left it in 1837. Hogarth's Rake's Progress hangs on hinged picture planes; the sarcophagus of Seti I sits in the basement crypt. Free, Wed–Sun 10:00–17:00.
Chamberlin, Powell and Bon's 1982 Brutalist city-within-a-city, built on 35 acres of Blitz rubble. The free Conservatory (Sundays only) holds 1,500 species under glass; the highwalks link three 42-storey towers and a lakeside terrace.
Founded 1753 on Hans Sloane's collection, now eight million objects. The Rosetta Stone, Parthenon sculptures and Sutton Hoo helmet sit under Norman Foster's 2000 Great Court roof — Europe's largest covered square. Free, 10:00–17:00.
Thomas Neale's 1690s sundial junction where seven streets converge — the pillar carries only six dials, the column itself being the seventh. Neal's Yard's painted courtyard hides behind an unmarked alley off Shorts Gardens.
Britain's densest Impressionist holding in eleven rooms: Manet's A Bar at the Folies-Bergère, Van Gogh's Self-Portrait with Bandaged Ear, Cézanne's card players. Reopened 2021 after a £57m refit. £16–20 adult, timed entry, 10:00–18:00.
A 340-seat Jacobean indoor theatre of oak and lime plaster, opened 2014 and lit entirely by beeswax candles on chandeliers lowered between scenes. Winter season runs Nov–April; tickets £10 standing gallery to £62 pit benches.
A Spitalfields silk-weaver's house staged as if the fictional Jervis family stepped out moments ago — half-eaten bread, guttering candles, chamber pots. Visitors move in total silence across ten rooms. £20 daytime, £30 candlelit evenings.
Six streets holding Europe's densest legal mural concentration — Banksy's stencils, Stik's stick figures, ROA's animals on Hanbury Street, and the rotating walls of Redchurch Street. Free, and the work changes month to month.
Opened 1901 in a Charles Harrison Townsend Arts and Crafts building; showed Picasso's Guernica to 15,000 East Enders in 1939 and gave Pollock, Rothko and Hockney their first UK exhibitions. Free entry, Tue–Sun 11:00–18:00.
The world's oldest surviving grand music hall, built 1859 behind a row of Georgian terraced houses in Wapping. Saved from demolition and conservation-repaired rather than restored — the peeling plaster is deliberate. Tickets from £15.
