21 Hidden Gems in London: Secret Spots Worth Finding (2026)

The City, Smithfield and Temple. Six places in the oldest part of London, all within a couple of miles of each other and most of them free. The City is quiet at weekends, but check the days: the Charterhouse opens Tuesday to Saturday and Temple Church mostly on weekdays.

St Dunstan in the East is the one I'd send anyone to first. It's a church that has been wrecked twice: burned in the Great Fire of 1666 and gutted in the Blitz in 1941. Wren's tower and steeple survived. In 1967 the City decided not to rebuild and turned the shell into a public garden, which opened in 1970. Now ivy and climbing plants hang off the Gothic window frames, there's a small fountain in what was the nave, and office workers eat lunch on the benches.

It's free and a short walk down from Monument, so it fits between the Tower of London and Borough Market without a detour. Open: daily 8am to 7pm or dusk, whichever is earlier. Tube: Monument or Tower Hill. The catch is that it's small and very photographed, so at lunchtime and on weekend afternoons you'll share it. Come early in the morning for the quiet version.

St Bartholomew the Great is billed as London's oldest parish church, founded more than 900 years ago by Rahere, a jester at Henry I's court. You walk in through a Tudor gatehouse above a 13th-century arch on West Smithfield, which once led into a much longer nave that was pulled down when the priory was dissolved in 1539. What's left is dark, heavy Norman stonework, and it looks nothing like the airy Wren churches around it. A young Benjamin Franklin worked as a printer in what is now the Lady Chapel, and Four Weddings and a Funeral was filmed here.

Entry is now free, with donations asked. Open: Monday to Saturday 10am to 5pm, and Sundays between services. Tube: Barbican or Farringdon. Weddings, concerts and filming can close parts of it, so don't cross London just for this; pair it with the Charterhouse a few minutes north and Postman's Park a few minutes south.

The Charterhouse started in 1348 as a burial ground for Black Death victims, became a monastery, then a Tudor mansion whose Great Chamber served as Elizabeth I's throne room before her coronation, and in 1611 it became an almshouse. It still is: residents aged 60 and over, called Brothers, live here and eat together in the Great Hall. The free museum by the entrance tells the story with 120 objects, curated with the London Museum, and you can walk into the chapel.

To see the Great Chamber and the old rooms you need the hour-long guided tour, £15 (£12 concessions), at 11am and 2.15pm. I'd book it; it's the only way into the best part. Open: Tuesday to Saturday 10.30am to 4.30pm, closed Sunday and Monday. Tube: Barbican or Farringdon. People live here, so no photos of residents and no tripods or selfie sticks.

Bunhill Fields is where London buried its religious dissenters from the 1660s: around 123,000 people, with more than 2,300 memorials. The names are the reason to come. William Blake, John Bunyan (author of The Pilgrim's Progress), Daniel Defoe (Robinson Crusoe) and the hymn writer Isaac Watts are all here, a few minutes' walk from the Old Street roundabout.

It's free and takes 20 minutes. Open: weekdays 8am, weekends 9.30am, until 7pm or dusk. Tube: Old Street or Moorgate. Most of the graves are behind railings in enclosed areas, so you see them from the paths rather than walking among them. Wesley's Chapel is directly across City Road.

Temple Church is hidden inside the Inns of Court, the lawyers' enclave between Fleet Street and the river, and plenty of Londoners have never been in. The round nave was built by the Knights Templar to copy the Church of the Holy Sepulchre in Jerusalem and was consecrated in 1185. Stone effigies of knights lie on the floor, including William Marshal, and it's the church in The Da Vinci Code.

Entry is £5 (£3 concessions, children free). The hard part is timing: sightseeing hours change daily, it's mostly weekdays around 10am to 4pm, and it's usually closed to visitors at weekends for weddings and services. Check the What's On page the morning you go. Tube: Temple or Blackfriars. The Twinings shop is a few minutes' walk away on the Strand, and Sir John Soane's Museum is 10 minutes north in Lincoln's Inn Fields.

Twinings at 216 Strand is opposite the Royal Courts of Justice, and it has been selling tea on this spot since Thomas Twining bought Tom's Coffee House in 1706. It's a narrow shop with a pick-and-mix wall of tea envelopes and a tasting bar at the back that usually has four or five teas on the go. Samples are free; just ask.

If you want more, the Classic Masterclass is £50 for two hours (18+), weekday afternoons and weekend mornings or afternoons. Open: 11am to 6pm most days, 11.30am to 6.30pm on Thursdays. Tube: Temple, two minutes. It's a shop, so 20 minutes is plenty unless you're doing a class, but it's a good stop between Temple Church and Covent Garden.

South Bank and Southwark. Four places south of the river, from Waterloo east to Rotherhithe. Leake Street and the Garden Museum work as a pair; Crossbones sits by Borough Market; the Brunel Museum is further east in Rotherhithe, on the Overground.

The Leake Street Graffiti Tunnel runs under the tracks of Waterloo station, and it's billed as London's longest legal graffiti wall: spray-painting here is allowed and actively encouraged. Artists repaint it constantly, so it looks different every week. Its reputation dates from 2008, when Banksy and other artists held a show here. The arches along one side now hold bars and cafés, including a board-game café and a Philly-style dive bar.

It's free, has no set hours and takes 15 minutes to walk through. Tube: Waterloo, Exit 6 (York Road), about five minutes. It smells of paint and it's gritty; it's a working tunnel, not a gallery. If you want to try it, the tunnel's own workshops are £50. Tripods and photo shoots need permission.

The Garden Museum is in the old church of St Mary-at-Lambeth, right next to Lambeth Palace on the river. The story it tells is John Tradescant's: gardener to Charles I, who's buried in the churchyard and whose collection of curiosities in Lambeth, the 'Ark', was Britain's first public museum. There's a Dan Pearson garden in the courtyard and a café.

Tickets are £16 on the door (£13-£16 online, by date), but the nave and garden are free, so you can look in without paying. Open: daily 10am to 5pm; it's closed all day on Wednesday 7 October 2026. Tube: Lambeth North, 10 minutes. The drawback right now: the 14th-century tower, 131 steps up (the climb Wenceslaus Hollar made in 1647 to draw his panorama of London), is closed for maintenance until later in 2026.

Crossbones Graveyard on Redcross Way is a paupers' burial ground where an estimated 15,000 people were buried until it closed in 1853. It's widely believed to have held the 'Winchester Geese', women who worked in the Bankside brothels licensed by the Bishop of Winchester in medieval Southwark. The iron gates are covered in ribbons, notes and flowers, renewed at a vigil held there at 7pm on the 23rd of every month. Behind them, volunteers have made a small garden with a pond and wildflowers.

It's free. Open: Wednesday, Thursday and Friday, plus the first Saturday of the month, 12pm to 2pm, and even that depends on volunteers. Outside those times you see only the gates, which are worth the five-minute detour from Borough Market on their own. Tube: Borough or London Bridge. The Old Operating Theatre is about five minutes' walk away.

The Brunel Museum is small, and the reason to come is the room underneath it. Marc Brunel and his son Isambard built the Thames Tunnel, opened in 1843 and the world's oldest underwater tunnel. You go down a staircase into its entrance shaft: about 50 feet across and 50 feet deep, walls still black with steam-train soot, and Overground trains rumble through the tunnel below your feet. Until 2016 you had to crawl through a hatch to get in.

Price: £10, under-16s free, including a guided tour at 12.30pm on Saturdays and Sundays. Open: Friday to Monday, 10.30am to 3.30pm, last entry 3pm (daily in school half-terms). Station: Rotherhithe on the Overground, under a minute away. Allow 45 minutes; there's no café on site.

Kensington. Two artists' houses eight minutes' walk apart, on one £23 joint ticket. Holland Park and its Kyoto Garden are between them, covered in the best parks in London.

Leighton House was the home and studio of the painter Frederic Leighton, and it's one of the most unexpected rooms in London. The Arab Hall, built from 1877 to 1881, is lined with Islamic tiles Leighton bought on trips to Turkey, Egypt and Syria (two panels came from Damascus in 1877), with a gold mosaic frieze and a fountain in the floor. It cost more than £7,000 to build, when the whole house had cost £4,500. Upstairs is his huge studio, and there's a café and garden you can visit free.

Price: £14 adult, £23 with Sambourne House; pay what you want on the first Monday of the month, 10am to 1pm. Open: 10am to 5.30pm, last entry 4.30pm, closed Tuesday. Station: Kensington (Olympia) or High Street Kensington. Same-day tickets are sold only at the desk, not online. Unlike its neighbor, it's step-free, by level access or lift.

Sambourne House at 18 Stafford Terrace is the opposite of Leighton's palace: a tall, cluttered Victorian family home, left almost exactly as it was. Linley Sambourne, chief cartoonist of Punch magazine, moved in in 1874, and the rooms are still packed with his furniture, pictures and William Morris 'Fruit' wallpaper. It's the best look inside a real middle-class Victorian house in London.

Price: £12, or £23 with Leighton House. Open: Wednesday to Sunday 10am to 5.30pm, closed Monday and Tuesday, so Wednesday to Sunday is when the joint ticket works. Free volunteer tours at 3pm on Wednesdays and Saturdays. Tube: High Street Kensington, 5 minutes. It's stairs all the way, five floors, starting with seven steep steps down to reception, so it's not an option for wheelchair users.

North and north-west. Two quieter green spots: the canal at Little Venice and a hidden garden on the edge of Hampstead Heath.

Little Venice is where the Grand Union and Regent's canals meet near Paddington, a pool lined with painted narrowboats, a waterside café and white stucco houses. It's a nice 20 minutes on its own, but the best way to use it is the London Waterbus, a narrowboat that runs from Browning's Pool along the Regent's Canal to Camden Lock in about 45 minutes. It goes through the Maida Hill tunnel and right through London Zoo, past the painted wolves' enclosure.

Price: £17 adult one way (£14 children, students and over-60s). There are no returns, so a round trip is two tickets; walking back along the towpath is the free alternative. Runs: daily through the autumn, four departures each way on October weekdays (11am, 12.15pm, 1.30pm, 2.45pm), more at weekends. Tube: Warwick Avenue (Bakerloo). It doesn't stop at the zoo, and there are around five steep steps to board, so it's not wheelchair accessible. Check whether you're booking the classic boat with live commentary or the wider cruiser without.

The Hill Garden and Pergola is on the West Heath side of Hampstead Heath, and most people walking the Heath never find it. The Pergola was built for the soap magnate William Lever (later Lord Leverhulme) with the landscape architect Thomas Mawson: a long raised walkway of stone columns and timber, draped in wisteria and vines, above a formal garden that was once a private estate's garden. It's free.

Two catches. It's on Historic England's Heritage at Risk Register, and there's maintenance scaffolding up now with some areas closed. And it closes early in autumn: 5pm from 5 October, 3.30pm from 25 October, 3pm from 16 November (2026). Tube: Golders Green, about 20 minutes' walk; I'd combine it with a walk across the Heath from Hampstead. No dogs except assistance dogs.

The East End. Four places, from the edge of the City out to Walthamstow. Wilton's is an evening; God's Own Junkyard is weekends only.

Wilton's Music Hall is a Victorian music hall down an alley near Tower Hill, and it looks it. John Wilton built the hall in 1859 behind a pub that had been known as the Mahogany Bar since about 1826. After a fire in 1877 left only the walls and the ten barley-twist columns that still hold up the balcony, it was rebuilt almost exactly as before. It was nearly demolished in the 1960s and saved after a campaign backed by John Betjeman. The peeling walls are kept as they are, on purpose.

The easy way in is the Mahogany Bar, which you can walk into for a drink most evenings (from 5pm on most days in the week of 28 September 2026, earlier on Wednesday and Saturday; closed Sunday; hours change weekly). To see the hall itself you need a show ticket or a £10 history tour, and the four autumn tour dates are already sold out, so a show is the realistic option. Tube: Aldgate East or Tower Hill, about 10 minutes.

The Viktor Wynd Museum of Curiosities is a basement on Mare Street in Hackney, down a spiral staircase, crammed with things you'd find in a Victorian collector's cabinet: a two-headed kitten, an eight-legged lamb, a 'mermaid' skeleton, mummified 'fairies', and some adult material. Upstairs is the Absinthe Parlour, a cocktail bar you can visit without a museum ticket.

Price: £12 for a 30-minute slot, £8 concession; on Thursdays it's £4 for everyone, walk-in only, which is the day I'd go. Open: Tuesday to Sunday from 3pm (noon at weekends), until late; closed Monday. Station: Cambridge Heath (Overground) or Bethnal Green (Central). It's small and gets crowded on Saturdays. Under-18s only with an adult before 5pm, and the stairs mean it's not accessible.

Tower Hamlets Cemetery Park opened in 1841 as one of London's 'Magnificent Seven' Victorian cemeteries, alongside Highgate and Brompton, and it's the only one in the East End. It stopped being a working cemetery long ago and has become 31 acres of woodland, meadow and leaning monuments, now a local nature reserve. It's much wilder and emptier than Highgate, and free.

Open: the side gates are open 24 hours; the main gate on Southern Grove is open dawn to dusk. Tube: Mile End. There are no public toilets, so plan around that. The 1km circular path is the easy way round, with step-free alternatives to the two sets of steps. If you liked this, Brompton Cemetery is the west London equivalent.

God's Own Junkyard is a warehouse on an industrial estate in Walthamstow filled floor to ceiling with neon: old Soho shop signs, fairground lights, film props. It was the collection of Chris Bracey, 'the Neon Man', who made signs for decades, including pieces seen in Eyes Wide Shut, Batman and Charlie and the Chocolate Factory. There's a café-bar inside, the Rolling Scones.

Open: Friday to Sunday only, from 11am; Sunday until 6pm. Friday and Saturday it's open until at least 9pm. It closes at 2pm on Saturday 24 October 2026 for a private event. No admission charge is listed on its site. Tube: Walthamstow Central (Victoria line), then a walk through Walthamstow Village along Orford Road. Phones only for photos; proper cameras aren't allowed.

Greenwich and south-east London. Three places beyond the reach of the Tube: the Painted Hall and the Fan Museum are 10 minutes apart in Greenwich, and Eltham Palace is a train ride further out. The rest of Greenwich, including the park and the free museums, is in free things to do in London.

The Painted Hall in the Old Royal Naval College is not exactly unknown, but most day-trippers to Greenwich head straight for the Cutty Sark and the Observatory and skip it. It shouldn't be skipped. Sir James Thornhill spent 1707 to 1726 painting more than 3,700 square meters (about 40,000 square feet) of walls and ceiling with about 200 figures, and it's billed as Britain's Sistine Chapel. Your ticket includes free talks every half hour from 11am and hourly tours.

Price: £19 adult, 16 and under free, and you can turn it into an annual pass at no extra cost. Open: daily 10am to 5pm, but closed all day Sunday 11 October 2026. Station: Cutty Sark (DLR). Two catches: £19 is a lot for one room, and the lift is out of order, so there's no step-free access for now. From 20 November to 7 February, the Peace Doves art installation hangs in the hall, same price.

The Fan Museum on Crooms Hill is the only museum in Britain devoted to fans, in a pair of early Georgian townhouses just off Greenwich Park. The collection runs to more than 4,000 objects, most of them fans, the largest collection of its kind in the UK, and it's the kind of small, specialist place that's more absorbing than it sounds.

Price: £5 adult, and free for seniors on Wednesdays. Open: Tuesday to Saturday 11am to 5pm, closed Sunday and Monday. Station: Cutty Sark (DLR), 5 minutes. The catch: its last temporary exhibition closed on 26 September 2026 and the next hasn't been announced, so check the site if the upstairs gallery matters to you. The Orangery is for private hire only; there's no public afternoon tea.

Eltham Palace is two buildings in one. The medieval Great Hall, from the 1470s, is part of the royal palace where Henry VIII spent his childhood. Right next to it, in 1936, the millionaires Stephen and Virginia Courtauld built an Art Deco mansion, and the interiors are the reason to come: a domed entrance hall, an Art Deco dining room, and Virginia's gold-plated bathroom. The gardens and moat are worth an hour on their own.

Price: from £15.38 (off-peak weekdays, booked online by the day before) to £22.70 (peak, on the day); £17 for a standard online adult ticket. Open: daily 10am to 5pm until 18 October, then 10am to 4pm, and weekends only from 2 November to 20 December and again from January to mid-February. Station: Mottingham by train, 10 minutes' walk; there's no Tube. Arrive by public transport and show your ticket for 20% off a walk-up ticket. The lift is out of service, so the upper floor is stairs only.
