01 — Founded 1078 by William the ConquerorTower of London:

The Tower has been a fortress, a royal residence, a prison, and a zoo over its 900-plus years, and today it holds the Crown Jewels, including the coronation regalia used at King Charles III and Queen Camilla's 2023 coronation. The White Tower, Bloody Tower, and Battlements are all included in general admission, and a Yeoman Warder tour comes with the ticket price rather than as an add-on.

Adult tickets run £37 online. Some rooms and routes currently have reduced access during ongoing conservation work, so check the Historic Royal Palaces website before your visit if a specific exhibit matters to you.

02 — Free Since Opening in 1759British Museum:

One of the largest and oldest museums in the world, holding the Rosetta Stone, the Parthenon sculptures, and Egyptian mummies across galleries that would take days to see in full. General admission costs nothing, though a timed entry slot is required to guarantee access during busy periods.

Special exhibitions carry a separate ticket price, but the permanent collection, which is most of what draws people here, stays free.

03 — Opened March 9, 2000London Eye:

The world's largest cantilevered observation wheel, 135 meters tall, with 32 glass capsules (one per London borough, with capsule 13 skipped). A full rotation takes 30 minutes, and on a clear day the view reaches Windsor Castle, 25 miles west.

Standard tickets run roughly £29-33 online, with prices shifting by date and demand. Fast Track tickets cost more but cut the wait significantly during peak hours.

04 — King Charles III's Official London ResidenceBuckingham Palace:

The 775-room palace has been the monarch's official London residence since Queen Victoria moved in in 1837. Charles currently lives at Clarence House while a decade-long reservicing project at Buckingham Palace continues, expected to finish in 2027, after which he and Queen Camilla plan to move in.

The 19 State Rooms open to the public for ten weeks each summer. In 2026, that's July 9 to September 27, daily 9:30am-7:30pm through August, then Thursday to Monday in September. Tickets cost £33 in advance or £37 at the door. The King's Gallery, holding rotating exhibitions from the Royal Collection, stays open most of the year separately.

05 — Coronation Site Since 1066Westminster Abbey:

Every English and British monarch has been crowned here since William the Conqueror in 1066, most recently Charles III in May 2023. The Abbey also holds the graves of 16 monarchs and has hosted 16 royal weddings, including Prince William and Catherine's in 2011.

Adult tickets run roughly £30. A National Rail 2-for-1 voucher applies if you arrive by train, and a summer VAT reduction has temporarily lowered prices between late June and early September 2026.

06 — Built 1894Tower Bridge:

Walking across the bridge itself is free. The paid Tower Bridge Exhibition adds the glass-floor walkway 42 meters above the Thames and the Victorian engine rooms that once powered the bascules. The bridge still lifts for river traffic on a published schedule, worth checking if you want to see it in action.

07 — Dome by Christopher Wren, 1710St Paul's Cathedral:

Climb 257 steps to the Whispering Gallery, where a whisper against the wall on one side carries clearly to the other, then continue up to the Stone and Golden Galleries for panoramic city views. The crypt holds Nelson's and Wellington's tombs.

Adult admission runs around £25. A working cathedral, so visiting hours shift around services.

08 — Free Since Founding in 1824National Gallery:

Over 2,300 European paintings from the 13th to the 19th century, including Van Gogh's Sunflowers and works by Vermeer and Caravaggio, sit on Trafalgar Square with no entry fee for the permanent collection.

09 — South KensingtonNatural History Museum:

The dinosaur skeletons and the blue whale skeleton suspended in the main hall make this one of London's strongest family draws, and it costs nothing to walk in. Special exhibitions, when running, carry a separate ticket.

17 — Former Bankside Power StationTate Modern:

Housed in a decommissioned power station on the South Bank, with the cavernous Turbine Hall as its centerpiece. The permanent collection of modern and contemporary art is free; major temporary exhibitions, like 2026's Frida Kahlo show, carry a separate ticket.

11 — Home to the Prince and Princess of WalesKensington Palace:

Queen Victoria was born here, and Diana, Princess of Wales lived here for years; today William and Catherine, the Prince and Princess of Wales, have their London apartment in the palace, though it's not open to visitors. What is open: Queen Mary's State Apartments and rotating exhibitions on royal women through history.

Adult tickets run £24.70. The 2026 ticket includes entry to a temporary exhibition on the history of the Punjab's princesses.

12 — Henry VIII's PalaceHampton Court Palace:

Henry VIII acquired this Thames-side palace from Cardinal Wolsey in the 1520s and expanded it into the sprawling complex you see today, including the Tudor kitchens that once fed the entire royal court. The garden maze and the Magic Garden are both included in general admission.

Adult tickets run £29. As at the Tower, some rooms and routes currently have reduced access during conservation work.

13 — World's Oldest, Largest Inhabited CastleWindsor Castle:

Built in the 11th century by William the Conqueror and continuously inhabited since, Windsor remains a working royal residence and one of King Charles's most-used homes. St George's Chapel, where Harry and Meghan married in 2018, sits within the grounds and is open to visitors most days.

Adult admission runs around £35. The castle sits roughly 30 minutes outside London by train, an easy half-day trip.

24 — Horse Guards, WhitehallHousehold Cavalry Museum:

A working museum where you can watch the Household Cavalry's horses being groomed and cared for in the stables, alongside uniforms, instruments, and artifacts tied to the regiment's actual ceremonial duties for the monarch.

10 — 350 Acres in Central LondonHyde Park:

One of London's largest Royal Parks, centered on the Serpentine Lake, where you can swim, take out a rowing boat, or in summer ride a solar-powered ferry. Speakers' Corner, at the park's northeast edge, has hosted public debate since the 1800s.

14 — Atop the "Walkie TalkieSky Garden:

A free, landscaped public garden offering 360-degree views of the City and the Shard from the top of 20 Fenchurch Street. The catch: tickets are released online every Monday morning for the following three weeks and sell out within minutes.

20 — Western Europe's Tallest BuildingThe Shard:

The View from The Shard, on floors 68-72, gives an unobstructed vantage point over the entire city from 244 meters up, a different and higher perspective than the London Eye or Sky Garden. Unlike Sky Garden, tickets here cost money but don't require the same scramble to book.

18 — Built to Commemorate the 1805 BattleTrafalgar Square:

Nelson's Column anchors the square, flanked by four bronze lions, with the Fourth Plinth rotating contemporary art installations on a multi-year schedule. The National Gallery sits directly on the square's north side, making the two an easy pairing.

19 — The Bell, Not the TowerBig Ben and the Houses of Parliament:

"Big Ben" technically names the bell, not the Elizabeth Tower it hangs in, a distinction most visitors never learn but locals will correct you on. The exterior and the famous silhouette across the river are free to view at any time; UK residents can apply for free tours inside, and international visitors can book paid tours when Parliament isn't sitting.

15 — One of London's Oldest Food MarketsBorough Market:

Trading on this site for over 1,000 years, Borough Market today runs dense with food stalls, from fresh produce to ready-to-eat dishes from a dozen different cuisines. Walking through costs nothing; budget for what you actually eat.

16 — Alternative Culture Since the 1970sCamden Market:

A sprawl of stalls along the Regent's Canal selling vintage clothing, handmade crafts, and street food, with live music spilling out of nearby pubs most evenings. Still one of London's most distinct neighborhoods for browsing rather than checking off a single sight.

22 — Pastel Houses, Saturday MarketNotting Hill and Portobello Road:

Rows of pastel-painted townhouses line the residential streets, and Portobello Road runs one of London's best-known antiques markets, busiest on Saturdays. A slower, photogenic alternative to the central tourist circuit.

25 — East London's Street Art DistrictShoreditch:

Large-scale murals cover walls throughout the neighborhood, changing periodically as new work goes up, alongside independent coffee shops, vintage stores, and a nightlife scene distinct from central London's. Best explored on foot, no fixed route required.

21 — UNESCO World Heritage SiteKew Gardens:

The Royal Botanic Gardens hold the world's largest collection of living plants, spread across 326 acres, with Victorian glasshouses including the Palm House as the architectural highlight. Kew draws around 2 million visitors a year, the most-visited paid attraction in this category.

Adult admission runs around £17, varying by season.

23 — Home of the Prime MeridianGreenwich and the Royal Observatory:

Stand with one foot in the Eastern Hemisphere and one in the Western at the Prime Meridian line, then walk up the hill in Greenwich Park for one of London's best skyline views back toward the city center. The historic town itself, the market, and the park cost nothing to wander; the Royal Observatory and the Cutty Sark each charge separate admission.
