Greater London · United Kingdom
Two thousand years of continuous settlement compressed into a city that runs a Roman wall, a medieval Tower, an imperial palace and some of the world's great free museums within a single Underground network.
London has been continuously settled since the Romans founded Londinium around AD 47, and the layers show, sometimes literally underfoot — a stretch of the Roman city wall still stands near the Museum of London, while the Tower of London's White Tower has watched over the city since 1078. Few capitals combine this depth of history with London's scale as a genuine present-tense world city: a financial centre, a theatre capital, and a city that absorbed more nationalities and languages into its daily life than almost anywhere else on earth.
The city's museums are, by any reasonable global standard, one of the great free cultural offerings anywhere — the British Museum, the National Gallery, the Tate Modern and the Natural History Museum all charge nothing for general admission, a legacy of a specific nineteenth-century decision that the nation's collections belonged to everyone. That alone reshapes how a London trip should be planned: the constraint is rarely money, it is time.
London is also, unavoidably, several cities in one. Westminster's palaces and government buildings sit a short walk from the City of London's Roman-founded financial square mile, itself walking distance from Shoreditch's converted warehouses and, across the river, the South Bank's cultural stretch and Borough Market's food stalls. Picking two or three neighbourhoods properly beats trying to see all of them badly.
Why visit
London's case is simple: nowhere else combines this depth of continuous history with world-class free museums and a genuine present-tense global-city energy.
The British Museum, National Gallery, Tate Modern and Natural History Museum all charge nothing for general admission — a rare, deliberate civic decision that changes how a trip should be planned.
Roman wall fragments, a Norman tower, medieval Westminster Abbey and a still-functioning royal palace, all within walking distance of each other and still part of the working city.
The West End rivals Broadway for quality and scale, with both blockbuster musicals and serious drama running in parallel, often at more accessible prices.
Over three hundred languages are spoken in London's schools, and the food, neighbourhoods and culture reflect a city built by immigration as much as by empire.
The Tube, whatever its reputation for delays, makes a sprawling city navigable, putting most major sights within a thirty-minute journey of each other.
Main attractions
London rewards more time than most first-time visitors budget. These eight are the ones worth building days around; the free museums alone could absorb a week.
Free to enter and holding several million years of human history — the Rosetta Stone, the Parthenon (Elgin) Marbles, Egyptian mummies and an Assyrian lion hunt frieze among a collection too large to see in one visit.
Tip Focus on two or three galleries per visit rather than attempting the whole museum. The Enlightenment Gallery is a good, less-crowded starting point.
A Norman fortress begun in 1078, home to the Crown Jewels, the ravens said to protect the kingdom, and nine hundred years of prisoners, executions and royal history within its walls.
Tip Book timed tickets online in advance — it sells out on peak days and the queue for walk-up tickets can be long.
A working abbey that has hosted every coronation since 1066, standing beside the Gothic Revival Houses of Parliament and Elizabeth Tower, home to the bell known as Big Ben.
Tip Book the Abbey ahead for a specific time slot. A Parliament tour, when sitting days allow, needs booking well in advance through your MP or directly.
The monarch's official London residence, its forecourt hosting the Changing of the Guard, with the State Rooms open to visitors only during the King's summer opening in August and September.
Tip Check the Changing of the Guard schedule before travelling — it does not run daily, especially outside summer.
A former power station turned world-class modern art museum, connected by the Millennium Bridge to St Paul's Cathedral, with the South Bank's riverside walk running past the Globe Theatre and Borough Market.
Tip Free general admission. Combine with a walk along the South Bank at golden hour for the best London skyline light.
Free to enter, on Trafalgar Square, holding Van Gogh's Sunflowers, Turner, Constable and one of the world's great collections of Western European painting from the thirteenth to the twentieth century.
Tip The collection is vast — pick up a free gallery map and plan two or three focused rooms rather than trying to see everything.
Two free museums in South Kensington, side by side — a diplodocus skeleton and a blue whale under a cathedral-like Victorian roof, and hands-on science exhibits spanning space, medicine and technology.
Tip Both are hugely popular with families — arrive at opening or accept genuine crowds by mid-morning, especially in school holidays.
A faithful reconstruction of the open-air Elizabethan theatre where Shakespeare's plays were originally performed, staging his works today in the same standing-yard, thatched-roof format.
Tip Standing tickets in the yard are cheap and give the most authentic experience — dress for the weather, as it is open to the sky.
Things to do
London rewards pairing one major sight with one neighbourhood a day, and building in real time for its free museums rather than rushing them.
From long-running musicals to serious new drama, London's theatre district rivals Broadway for quality, often at more accessible prices, with day-of and preview discounts available for the flexible.
Tip Check TodayTix and official theatre box offices for day seats and returns, which can be significantly cheaper than advance full-price tickets.
A historic food market beside London Bridge, stalls selling everything from artisan cheese to street food from a dozen cuisines — one of the best lunch options in the city.
Tip Come hungry and share dishes between stalls rather than committing to one large meal at a single vendor.
Hyde Park, Regent's Park, St James's Park and Greenwich Park all offer genuine green space and quiet within the city, a useful counterweight to London's density and pace.
Tip Greenwich adds the Royal Observatory and the Prime Meridian line to the park itself — worth the DLR trip out.
The Tube is the fastest way to cover London's real distances, and a contactless card or Oyster card works seamlessly across it, buses and the Overground.
Tip Avoid rush hour (roughly 8–9:30am and 5–6:30pm) if you can — the network is crowded at peak times.
A Thames river boat between Westminster and Greenwich or the Tower gives a different, unhurried perspective on the skyline and passes most of the city's major landmarks in sequence.
Tip Travelcards and Oyster pay-as-you-go discounts often apply to certain river bus services, not just the Tube and buses.
Neighbourhoods like Shoreditch, Notting Hill, Camden and Greenwich each have their own distinct character, markets and food scenes well worth the short Tube ride from central London.
Tip Camden Market and Portobello Road (Notting Hill) are both best visited on their specific market days for the full atmosphere.
Local food
London's food scene reflects its population as much as its own traditions — excellent British, and excellent everything else besides.
Roast meat, potatoes, vegetables and Yorkshire pudding, the definitive London Sunday institution, best had at a proper pub rather than a chain restaurant.
Where to try it Neighbourhood pubs across the city — ask locally, since the best ones are rarely the most central or famous.
Battered fish and chips, done properly, remains one of London's best simple meals, though quality varies enormously between a good chippy and a tourist-trap one.
Where to try it Poppies in Spitalfields or a local chippy away from the main tourist strips.
Eggs, bacon, sausage, beans, grilled tomato and toast, a genuine daily ritual across the city's cafes rather than a tourist performance.
Where to try it Traditional 'greasy spoon' cafes across the city, particularly in the East End.
London's Bangladeshi and wider South Asian food scene, concentrated historically around Brick Lane, represents one of the city's most significant culinary contributions and remains excellent.
Where to try it Brick Lane's curry houses, though increasingly it is worth exploring beyond the main strip for the best value and quality.
Finger sandwiches, scones with jam and clotted cream, and pastries, served formally over several courses — a genuine London institution rather than just a tourist photo opportunity.
Where to try it Traditional hotels for the full formal experience, or more affordable versions at independent tearooms across the city.
Beyond Borough Market, markets across the city showcase London's food diversity — everything from Ethiopian to Filipino to modern British, changing with the city's population.
Where to try it Borough Market, Maltby Street Market and Broadway Market, each with a slightly different character and vendor mix.
Accommodation
London is large enough that neighbourhood shapes the trip. The choice is mainly between central convenience and a more local, better-value stay a short Tube ride out.
Transport
London has multiple major airports and is the natural hub of Britain's rail network, making it the default start or end of most UK trips.
London's Underground, buses and Overground form one of the world's most extensive urban transport networks, covering nearly every sight in this guide.
When to go
London's museums and theatres work year-round, which makes weather and crowds, rather than opening seasons, the main factors in timing a visit.
Mild, with parks and gardens at their best and crowds still below the summer peak. April can be wet, so pack accordingly.
The best odds of warm weather and long daylight hours, alongside the year's biggest crowds and highest hotel prices, particularly in August.
Often the best-kept secret: comfortable temperatures, autumn colour in the parks, and noticeably thinner crowds than summer.
Short, often grey days, but the Christmas lights, markets and West End pantomime season give the city a genuine seasonal atmosphere, and hotel prices drop outside the December peak.
Worth planning around: Late July and August's school-holiday crush pushes prices and crowds to their annual peak at the major sights and museums.
Itinerary
One major sight and one neighbourhood a day, with real time built in for the free museums rather than a rushed pass-through.
The seat of government, then the South Bank.
A full day given to the British Museum and Trafalgar Square.
Royal history, then London's financial heart.
The palace, then the museum quarter.

FAQ
Four to six. That gives a day for Westminster and the South Bank, a full day for the major free museums, a day for the Tower of London and the City, and a day for Buckingham Palace and South Kensington's museums. Three days is possible but rushed given how much is free and worth lingering in.
The Tower of London, which sells out on peak days. Popular West End shows, especially long-running hits. Any Parliament tour, which needs booking well ahead. The great museums — British Museum, National Gallery, Natural History Museum — are free and generally do not need advance booking, though special exhibitions within them often do.
May to June and September. Both offer mild weather and manageable crowds. Summer brings the best odds of sunshine and the biggest crowds; winter is atmospheric around Christmas but cold, grey and short on daylight.
Covent Garden or the West End for first visits and theatre access. South Bank or Southwark for museums and river views. Shoreditch for nightlife and better value. Kensington for the museum quarter and a quieter residential feel. All are well connected by Tube.
Yes, the most expensive city in this guide, running roughly £150–280 per person per day mid-range. The free museums offset this significantly — a huge part of what makes London worth visiting costs nothing to see.
Yes, with ordinary vigilance. Violent crime against visitors is rare. Pickpocketing occurs in crowded tourist areas and on the Underground — keep bags zipped and phones out of back pockets, and the practical risk largely disappears.
A Sunday roast at a proper pub, fish and chips away from the tourist strips, and curry on or near Brick Lane, one of the city's most significant culinary contributions. Afternoon tea for a genuine occasion, and the food markets — Borough above all — for a cross-section of everything the city now cooks.

Transport
European rail is excellent and confusing — six national operators, three completely different pricing models, and a rail pass that is either a bargain or a waste depending on where you are going. Here is how to work out which.
Planning
Most first European trips go wrong in the same three ways: too many cities, too little time in each, and a route shaped by a cheap flight rather than by geography. Here is how to avoid all three.
