The restoration of the nave was completed in September 2004, and this church is still a striking building designed by Sir Nicholas Hawksmoor with a particularly tall, pointed spire. Hawksmoor's design was significantly altered in the 19th century, and present continuing restoration is intended to restore it to Hawksmoor's original vision. Christ Church was built as part of the 50 Churches for London project.

The main, central square of London, Trafalgar Square is associated with celebration and demonstration - it is the site of London's lacklustre New Year celebrations, and in 2003 was the site of the triumphant homecoming of the British Rugby team from the World Cup, and a centre for demonstration against Britain's involvement in the Iraq War. The square has been associated with the many hundreds of pigeons that used to be found here, but in 2003 a bylaw was passed to make it illegal to feed them. Nelson's Column, surrounded by the four bronze lions can be found here, on the south side of the square. The north-west plinth in the square was intended to hold an equestrian statue of William IV, but remained bare since 1841 due to insufficient funds. Since 1999, it has been used to display controversial contemporary sculpture. Houses the British national collection of western European art dating from the 13th to 19th centuries. A truly awe-inspiring collection, notable works include Hans Holbein's The Ambassadors, Van Gogh's Sunflowers and Constable's The Haywain. The vast majority of art is free of charge to visit. Temporary exhibitions are generally fairly costly, but invariably well researched and presented. The audioguides are very comprehensive, have comments on most of the paintings in the museum, and are free though this fact is not advertised. A donation is suggested. In addition to courses, workshops, lectures and other events, the National Gallery has free talks and tours every day. The National Portrait Gallery is just around the corner from the National Gallery and is an entertaining way to learn about British history since the Tudors. Visitors walk around the gallery chronologically, viewing portraits of notable figures from British history - from Henry VII, painted by Hans Holbein, to Blur, painted by Julian Opie. The High Commission of Canada immediately opposite to Trafalgar Square maintains a regular art exhibition featuring Canadian artists.

Named in honour of Queen Victoria and her consort Prince Albert, this museum has existed for over 150 years. It contains a huge collection of decorative arts from all over the world and far back in time. Trying to see everything in one day would be exhausting, so use the excellent maps the V&A provides to plan where you want to go. There are regular exhibitions concentrating on a particular theme from Chinese art to fashion designers. Frequently they put on children's activities and late DJ nights.

Designed and built in 1619-1622 by the Neo-Classical architect Inigo Jones, The Banqueting House is now all that remains of Whitehall Palace, the sovereign's principal residence from 1530-1698 when most of it was destroyed by fire. Renowned for its architecture and paintings (by Rubens, among others), the building is also famous for being the scene of Charles I's execution in 1649 at the end of the English Civil War.

A vast collection of cartoons and comics on display with special, often topical, exhibitions.

Founded in 1123, by jester-turned-monk Rahere, this Norman church is one of the oldest in London. It was damaged in the Dissolution but managed to escape both the Great Fire and the Blitz. This is a Grade I listed building. Tourists are welcome when services are not in progress and are charged an admission fee (which does not apply to those coming to pray or use the café).

The great domed cathedral of St Paul's, designed by Sir Christopher Wren to replace the Gothic medieval cathedral destroyed in 1666 in the Great Fire of London, was built between 1675–1710. Of the most famous London sights, St Paul's is the one most conveniently located for the Barbican. It's a significant building in British history, having been the site of the funerals of several British military leaders (Nelson, Wellington, Churchill), and significantly held peace services marking the end of the two world wars. The cathedral is also famous for its Whispering Wall, as well as its stunning view over the city. The crypt is also open to the public, holding the tombs of Nelson, Wellington and Christopher Wren. It is possible to sidestep the admission charge by entering for one of the midday services, even if you don't take part, or for the daily choral evensong in the late afternoon. However, you'd still need a ticket to get to the top. Photography is not allowed.

In many cities a local transport museum would be of very narrow interest - not London, however! London's public transport is iconic, and the story of how it developed from horse and cart through early buses, Tube trains and trolleybuses to the present day is well worth coming to find out about. There is plenty of opportunity to clamber aboard the historic buses and Tube trains on display. Also, because London's transport is so well known, the museum shop contains plenty of items that make interesting and original gifts and souvenirs.

A treasure trove of antique toys exhibited in a warren of 6 rooms above the toy shop of the same name. A very charming place indeed, though the doll rooms are a bit gruesome.

This gallery houses the Tate collection of British art from 1500 through to contemporary art. A side wing collects together the gallery's collection of paintings by Turner, including some stunning seascapes. Temporary exhibitions are exceedingly varied: examples include exhibitions of Turner's paintings of Venice and the work of photographer Wolfgang Tillmans. The best known exhibition is the Turner Prize, consists of works by four artists shortlisted for the annual contemporary art prize, which runs from late October to January each year.

Probably the most colourful event in the UK's legislative calendar, this takes place in May or June every year, or after a general election, when the King travels to the Houses of Parliament to open the new parliamentary session. During this event, the Lords, Speaker of the House of Commons, and other office holders can be seen dressed in their ceremonial robes, and there is always an elaborate procession when the King makes his way to the Houses of Parliament from Buckingham Palace. This is one of the few occasions where all branches of the British government are gathered in the same place. Many traditions of the State Opening can trace their origins to a more turbulent past, when the relationship between the monarch and Parliament was sometimes antagonistic. In particular, since the English Civil War, the monarch has been banned from entering the House of Commons chamber, and instead must send a representative (the Black Rod) to summon the MPs to the Lords chamber, where he delivers his speech. Another notable tradition is the holding of a Hostage MP in Buckingham Palace, ostensibly to guarantee the safe return of the monarch, who is released once the King has returned to the palace safely after delivering his speech. While attendance at Parliament itself is limited to special guests that have been invited by the Prime Minister, it is broadcast live on the BBC, and you can also view the King's procession from Buckingham Palace to Parliament from the roadside for free.

After leaving its brutalist skyscraper on Old Broad St, the London Stock Exchange now resides on Paternoster Sq. Dating back to 1698, it is one of the world's oldest and largest stock markets.

Dedicated to scientific exhibitions and collections bar those related to the life sciences. A number of famous historical machines and inventions are housed here, from steam locomotives to the Apollo 10 command module. The space exhibits are especially popular. Exhibitions tend to concentrate on explaining scientific principles with working models and there is a strong emphasis on education and attracting children. The Science Museum opened a "Children's Gallery" in the 1930s and it continues to lead the way in this area; now, there are three separate galleries aimed at all ages of younger visitor, from 5 to 16. The museum also runs "Science Nights" whereby children spend an evening learning principles and participating in experiments before spending the night sleeping in the museum with the exhibits. Also houses a vast library of scientific and medical books and journals.
