London wears its history in stone, glass and gilt, and its landmarks are scattered across a compact, walkable core. This guide gathers the capital's defining sights, grouped by area so you can build a sensible route rather than zig-zag across the city. It is written for the visitor who wants to see the essentials properly, understand what each place is known for, and avoid the queues and missteps that swallow a day.
The Tower of London and Tower Bridge
The Tower of London is a fortress, former royal palace and prison on the north bank of the Thames, home to the Crown Jewels and guarded by the Yeoman Warders. Tower Bridge, the Victorian bascule bridge beside it, is often confused with London Bridge but is the one with the twin towers and high-level walkways.
Arrive early at the Tower to reach the Crown Jewels before the crowds, and join a Yeoman Warder tour for the sharpest introduction to the site. Allow two to three hours for the complex as a whole.
- Nearest Underground: Tower Hill on the Circle and District lines.
- See the Crown Jewels, the White Tower armouries and the resident ravens.
- Walk across Tower Bridge for views back over the fortress and the river.
Westminster: Big Ben, the Abbey and Parliament
Westminster holds the cluster most people picture as London: the Houses of Parliament, the clock tower whose great bell is Big Ben, and Westminster Abbey, the Gothic church where monarchs are crowned and many are buried. The three sit within a few minutes of one another on the river's north bank, beside Parliament Square.
This is the city's ceremonial heart, and it rewards a slow walk. Cross Westminster Bridge for the classic view, then continue along Whitehall past the Cenotaph and Downing Street towards Trafalgar Square.
- Nearest Underground: Westminster on the Jubilee, Circle and District lines.
- Westminster Abbey holds Poets' Corner and the Coronation Chair.
- Tours inside Parliament are possible when the Houses are not sitting.
The South Bank: London Eye, the Shard and Tate Modern
The South Bank is the riverside walk along the Thames opposite Westminster and the City, lined with modern landmarks. The London Eye is the giant observation wheel beside County Hall, Tate Modern is the free contemporary art gallery in a former power station, and The Shard is the tall glass spire at London Bridge with a viewing gallery near its summit.
The riverside path strings these together over a pleasant hour or two of walking, passing the Royal Festival Hall, Shakespeare's Globe and Borough Market along the way. It is one of the best free walks in the capital, and you can dip into the galleries listed in our London museums hub as you go.
- Nearest Underground: Waterloo, Southwark and London Bridge serve different ends of the walk.
- For high views, choose between the London Eye, The Shard or the free Sky Garden across the river.
- Tate Modern's permanent collection is free to enter.
The City: St Paul's Cathedral and the modern skyline
St Paul's Cathedral is Sir Christopher Wren's domed masterpiece in the City of London, the financial district that occupies the site of the original Roman settlement. Around it rise the clustered towers known by their nicknames, including the Gherkin and the Walkie-Talkie, the latter crowned by the free public Sky Garden.
St Paul's rewards the climb to the dome's galleries for the famous Whispering Gallery and wide views across the river to Tate Modern, reached on foot via the Millennium Bridge. The City is quietest at weekends, when the office crowds thin.
- Nearest Underground: St Paul's on the Central line.
- Book Sky Garden tickets in advance, as free slots go quickly.
- Cross the Millennium Bridge to link the City with the South Bank.
Royal London: Buckingham Palace and the parks
Buckingham Palace is the monarch's official London residence at the end of The Mall, best known for the Changing of the Guard ceremony at its forecourt. It sits between St James's Park and Green Park, with Hyde Park and Kensington Gardens a short walk west, forming a continuous green spine through the centre of the city.
The State Rooms open to visitors during the summer, when the court is away. Check the schedule for the Changing of the Guard before you set out, as it does not run every day and is affected by weather.
- Nearest Underground: Green Park and St James's Park.
- Walk The Mall from Trafalgar Square through Admiralty Arch for the approach.
- St James's Park offers the prettiest views back towards the palace.
How to plan a landmark walking route
The simplest approach is to follow the Thames, which threads past most of the essential sights in a single line. A classic full-day route runs from the Tower of London westwards along the river to Westminster, crossing bridges to take in both banks, then turning up to Buckingham Palace and the royal parks.
Group the sights by area to save time, wear comfortable shoes, and lean on the river crossings rather than the Underground for short hops. For more structured plans, see our London itineraries, and for sights that cost nothing, our guide to free things to do in London.
- Start east at the Tower and walk west with the morning light behind you.
- Use Westminster, Waterloo and London Bridge as natural break points.
- Pre-book timed entry for the Crown Jewels, The Shard and Sky Garden.
London Landmarks FAQ
What are the must-see landmarks in London?
The essential landmarks are the Tower of London, Tower Bridge, the Houses of Parliament with Big Ben, Westminster Abbey, Buckingham Palace, St Paul's Cathedral, the London Eye and The Shard. Most line the River Thames within the central core, so they can be combined comfortably across one or two days of walking.
Can you see London's landmarks in one day?
Yes, the central landmarks can be seen in a single full day if you focus on exteriors and views rather than entering every building. Walk the Thames from the Tower of London to Westminster, then up to Buckingham Palace. To go inside places such as the Tower or St Paul's, allow two days.
Which London landmarks are free to visit?
Many of London's landmarks cost nothing to admire from outside, including Tower Bridge, Buckingham Palace and Big Ben. Tate Modern's permanent collection and the Sky Garden viewing levels are free, as is walking the South Bank and crossing the Millennium and Westminster bridges for landmark views.
What is the difference between Tower Bridge and London Bridge?
Tower Bridge is the ornate Victorian bascule bridge with two towers and high walkways beside the Tower of London, and it is the one most visitors photograph. London Bridge is the plainer crossing just upstream. The two are frequently confused, but the famous one with the towers is Tower Bridge.
Where is the best view over London's landmarks?
The highest paid viewpoints are The Shard near London Bridge and the London Eye on the South Bank. For a free alternative, the Sky Garden atop the Walkie-Talkie tower offers wide City views with advance booking. The dome galleries at St Paul's give a more historic vantage.
