London Invented the Traffic Light, Buried a Roman Temple Under a Bank, and Charges You More to Get to Heathrow Than Almost Any Other Airport on Earth

The world’s first traffic light was installed in 1868 directly outside the House of Commons. It exploded and injured a policeman. London has been inventing things and immediately breaking them ever since. The city’s talent for coexisting with its own contradictions is what makes it so consistently interesting to visit, and also, occasionally, baffling.

Getting In and Getting Around

Heathrow is the main international gateway, and the Elizabeth line (purple on the tube map) runs from Heathrow terminals to central London in about 25 minutes. The catch is cost: TfL charges peak rates for Heathrow connections regardless of what time you travel, so a single journey from Heathrow to Zone 1 runs around 15.50 pounds in 2026. The Piccadilly line is slower (45 to 55 minutes) but significantly cheaper at standard Zone 6 fares with an Oyster card.

Pay-as-you-go with a contactless bank card works identically to an Oyster card throughout the tube, bus, Overground, DLR, and Elizabeth line networks. You do not need to buy a separate Oyster card unless you specifically want one. Touch in and out at the yellow readers at every station, and the system applies the correct fare and daily cap automatically. In 2026, the Zone 1-2 daily cap is 8.90 pounds, which is what most visitors will spend on a full day of sightseeing in central London. Fares increased by an average 4.6% in March 2025.

Peak hours run Monday to Friday, 6:30am to 9:30am and 4pm to 7pm. Outside those windows, single fares in the central zone drop from around 3.60 to 3.10 pounds. It is worth adjusting plans around this if cost is a concern.

Where to Go

The British Museum on Great Russell Street holds roughly eight million objects, of which about 80,000 are on display at any one time. Entry is free. The Rosetta Stone, the Elgin Marbles, the Sutton Hoo helmet, and the Lewis Chessmen are all here. Arriving when the doors open at 10am means you reach the most popular galleries before the tour groups.

Beneath Bloomberg’s European headquarters near Bank station, at the site of their discovery in 1954, the Temple of Mithras sits reconstructed at its original Roman depth. Admission is free and the space is intentionally atmospheric. The temple was built around AD 240 and is one of the most significant Roman remains in northern Europe. It receives a fraction of the attention given to the Tower of London and is considerably more interesting than most visitors expect.

The Tower of London charges 34 pounds for adult admission (2026 prices; children under 5 free). The Crown Jewels and the Yeoman Warder tours are the primary draws, but the medieval palace rooms on the upper floors are worth the extra time and rarely crowded. Book tickets online; walk-up queues on busy days can be long.

The V&A East Museum opened in April 2026 in Queen Elizabeth Olympic Park, Stratford, with opening exhibitions focused on Black British music history and access to a significant portion of the V&A’s permanent collection including items from the David Bowie archive. The Stratford location means it is less tourist-centric than the South Kensington original and noticeably less crowded.

The Painted Hall at the Old Royal Naval College in Greenwich is the building most travel writers forget to mention and one of the most extraordinary interiors in Britain. Sir James Thornhill painted the ceiling between 1707 and 1726, covering 40,000 square feet with allegorical scenes celebrating British naval power. It is compared to the Sistine Chapel with some legitimacy. Greenwich is 15 minutes from central London by Elizabeth line to Canary Wharf, then a short DLR ride, or 30 minutes by river boat from Westminster Pier.

What to Skip (or Reconsider)

The London Eye at 34 pounds per adult is expensive for what amounts to a slow Ferris wheel, and the views, while good, are not dramatically better than those from the free Sky Garden in Fenchurch Street (booking required, no charge), the observation level of St Paul’s Cathedral (21 pounds), or the top floor of Tate Modern (free).

Where to Eat

Dishoom, the Bombay-style cafe group, remains one of the better restaurants in London at any price point, not merely among the “worth-it” category. The Covent Garden branch is typically the easiest to get into; the Shoreditch original has the longest queues, though they move with reasonable speed. Reserve online at least a week ahead for evenings.

Padella in Borough Market serves fresh pasta at lunch prices that feel like a small error. The pici cacio e pepe is the dish. Queue from about 11:45am before the 12pm opening to avoid a long wait.

Borough Market itself, on Southwark Street under the railway arches, is at its best Thursday through Saturday. The prepared food stalls are genuinely good. The market was established in the 13th century, though the current Victorian ironwork is from 1851.

Leadenhall Market in the City, a 14th-century covered market with Victorian Gothic ironwork, is quieter than Borough and worth walking through for the architecture as much as the food. It appeared as Diagon Alley in the early Harry Potter films, which is why there are always a few people with cameras standing in the entrance looking triumphant.

Where to Stay

The Ritz on Piccadilly (from around 700 pounds per night) is the benchmark luxury option and maintains standards that justify the price if price is not your primary concern. The Goring in Belgravia has been family-run since 1910, smaller and less ostentatious than the Ritz, and the garden is one of the better hotel gardens in central London.

The Hoxton group operates several hotels across London including Shoreditch, Holborn, and Southwark. Rates run from around 120 to 220 pounds depending on property and dates. The rooms are well-designed and smaller than the rates might suggest, but the locations are good.

For longer stays or groups, self-catering apartments in Clerkenwell, Bermondsey, or south Hackney offer more space at lower per-night costs than central hotels, with good transport connections.

Theatre and Evening

The West End concentrated along Shaftesbury Avenue and the surrounding streets runs more shows simultaneously than New York’s Broadway. In 2026, notable productions include the Beetlejuice musical (from May), Hercules (from June), and The Great Gatsby. Tickets for most shows are available through the official venue box offices at face value; third-party resellers typically add 20 to 40% in fees. The TKTS booth in Leicester Square sells same-day and next-day tickets at genuine discounts for shows with availability.

Day Trips

Windsor Castle, 30 minutes from London Paddington by Great Western Railway (around 12 pounds return), is open most days except Tuesdays and Fridays when it hosts state engagements. The State Apartments and St George’s Chapel are the primary attractions; admission runs 32 pounds for adults.

The practical rule for London: buy attraction tickets online in advance for anything that charges admission, plan around tube peak hours if travelling by public transport, and keep at least one full afternoon without an agenda. The city rewards walking in ways that a timetable cannot accommodate.
