There’s a version of London that lives entirely in guide books and Instagram grids. The Tower Bridge shot. The red phone box. The queue for the London Eye. It’s not bad London. It’s just not all of London.
The city has been accumulating layers for over two thousand years. Inside all that history, all that density, all those streets that turn unexpected corners — there are places that most visitors never find. These are fifteen of my favourites.
The List
1. Sir John Soane’s Museum, Holborn
One of the strangest and most extraordinary buildings in London. The architect Sir John Soane left his house to the nation in 1837 and it has barely changed since. Inside: an Egyptian sarcophagus, Hogarth paintings, and architecture that somehow fits more space than physically seems possible. Entry is free. Visit on a Tuesday evening when they open by candlelight.
2. The Sky Garden, Fenchurch Street
The free rooftop garden inside the “Walkie Talkie” building offers one of the best elevated views of London. Book free tickets in advance at skygarden.london — they go fast.
3. Neal’s Yard, Seven Dials
A tiny courtyard hidden behind Seven Dials, painted in every colour imaginable. It feels like a film set, except it’s real, and it’s been here for decades.
4. The Painted Hall, Greenwich
Often called London’s Sistine Chapel. The ceiling and walls were painted by Sir James Thornhill over 19 years in the early 18th century. Free to visit and genuinely mind-bending.
5. Leake Street Arches, Waterloo
Hidden beneath Waterloo station is London’s longest legal graffiti tunnel. The murals change constantly. On weekends it fills with street food and live music.
6. The Pergola and Hill Garden, Hampstead
A Grade II listed Edwardian pergola hidden inside Hampstead Heath, overgrown and romantically dilapidated. In summer, when the wisteria is out, it’s one of the most beautiful places in the city.
7. God’s Own Junkyard, Walthamstow
A warehouse full of neon signs, vintage advertising, and illuminated art in East London’s Blackhorse Lane. Open weekends — check their website before visiting.
8. The Dennis Severs’ House, Spitalfields
A Georgian townhouse preserved as it might have been in the 18th century. Candles flicker, food sits half-eaten on the table, coats hang on chairs. Eerie and completely unlike anything else in London.
9. Crossbones Garden, Southwark
A tiny memorial garden dedicated to the “outcast dead” — the paupers of medieval Southwark buried here in unhallowed ground. The gate is covered in ribbons and offerings. Quiet, strange, and moving.
10. Cecil Court, Covent Garden
A pedestrian lane lined with antiquarian booksellers, old maps, and vintage film posters. It’s been here since at least the 17th century. Allegedly the inspiration for Diagon Alley.
11. The Crystal Palace Dinosaurs, Crystal Palace Park
Life-sized Victorian dinosaur sculptures — incorrectly but wonderfully rendered according to 1854 science — arranged around a lake in South London. Grade I listed, absurd, and brilliant.
12. The Barbican Conservatory
Inside the Barbican Centre sits a tropical greenhouse with over 2,000 species of plants, fish, and terrapins. Opens to the public on Sundays — check the Barbican website for current times.
13. Postman’s Park, City of London
A small garden in the City with one extraordinary feature: a Victorian memorial wall covered in ceramic tiles, each commemorating an ordinary person who died saving someone else’s life. One of the most affecting places I’ve found in London.
14. The View from One Tree Hill, Honor Oak
A quiet hilltop park in South London with a panoramic view of central London — completely free, rarely visited by tourists, and offering a view you’d pay £30 for elsewhere.
15. The Wapping Hydraulic Power Station
A former Victorian industrial building in East London repurposed as a gallery and event space. The architecture alone makes it worth seeking out — check what’s on before visiting.
London’s best moments often happen away from the queues. The city is built for getting lost — and when you do, you find things like these: a medieval garden with a memorial wall, a rooftop full of neon, a room that hasn’t moved in 200 years.
FAQ
Q: Are all of these spots free?
A: Most are entirely free — Sir John Soane’s, the Painted Hall, Postman’s Park, One Tree Hill, Leake Street, Neal’s Yard, and the Sky Garden (free, requires advance booking). The Dennis Severs’ House charges entry.
Q: Which one would you recommend for a first visit?
A: In my experience, Sir John Soane’s Museum is the most reliably extraordinary. Nothing else in London quite prepares you for it.
Q: How do I get to God’s Own Junkyard?
A: It’s in Walthamstow, a short walk from Blackhorse Road Tube station on the Victoria line. Check their website before visiting — hours vary and they’re typically open Thursday to Sunday.
Q: Are these suitable for children?
A: Several are brilliant for families — the Crystal Palace Dinosaurs, the Barbican Conservatory, and the Sky Garden especially. The Dennis Severs’ House suits older children and adults.
Q: Do I need to book in advance for any of these?
A: Yes — the Sky Garden requires free advance tickets via skygarden.london. The Dennis Severs’ House requires booking. All others can generally be visited without prior booking, though always check the venue website.
Q: Can I visit several of these in one day?
A: Group by area for efficiency: Cecil Court and Sir John Soane’s are both near Holborn. Leake Street and Crossbones Garden are both south of the river near Waterloo/London Bridge. Postman’s Park is in the City and pairs well with the Sky Garden.
Q: When is the Barbican Conservatory open?
A: Typically Sundays from noon, and occasionally during special events. Check barbican.org.uk for current times.
Q: What’s the best hidden gem for a romantic visit?
A: The Pergola and Hill Garden at Hampstead Heath in summer. It’s genuinely magical.
Q: Is Wapping safe to visit?
A: In my experience, yes — it’s a residential area with strong maritime history and perfectly pleasant to visit during the day.
Q: Are these actually unknown, or just less well-known?
A: A fair question. None are genuinely secret — many have Instagram followings. But in my experience, they’re significantly less visited than the main attractions, and they all reward discovery.
