Tate Britain

All non-classified government documents can be read and photographed here, with a (free) reader's card having been obtained. There is also a small museum, which does not require the card to access.

Site of the London residences for the Prime Minister (No. 10) and the Chancellor (No. 11).

The Wallace Collection is one of the world's finest private art collections, the best known of which is Frans Hals's work The Laughing Cavalier. Other artists on display include Rembrandt, Titian, Poussin, and Reynolds. This is well worth escaping to after the hustle and bustle of Oxford Street.

The main sights to see in London's Chinatown are the expressions of Chinese culture and Eastern ambience in Chinatown, and for a good Chinese meal. There are few souvenir shops for tourists and no museums or temples. The three ornamental Chinese arches are worth a look. Chinatown does incorporate some entertaining combinations of British and Chinese culture, such as the phone booths with pagoda-style sloping roofs.

The second biggest greenhouse in London, containing over 2,000 species of tropical plants as well as birds and fish.

The main headquarters of the Worshipful Company of Fishmongers and a Grade II* listed building.

Grade I listed Saxon church founded before the 12th century. The exterior was mostly constructed in the 15th century, and the interior in the 19th. The north side of the church houses a musician's chapel opened in 1955. In addition to the services, there are often evening (chargeable) concerts.

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.

Properly St Lawrence Jewry next Guildhall, it is the official church of the Lord Mayor of London.

Now preserved by the National Trust, this 18th-century house was the home of the historian Thomas Carlyle from 1834 and now houses a museum dedicated to his life and work.

A small realm of serenity in the midst of the typical turmoil. It used to be the court of the Knights Templar. You can still visit the beautiful Romanesque church, which is one of the oldest ones in London (opened in 1185) and has connections to the order of Templars. The chancel of the church was built by Henry III. The church still serves the members of Gray's Inn and Lincoln's Inn and has frequent services open to the public. Fans of Dan Brown's The Da Vinci Code will recognise the church from both the novel and the film.

The London Mithraeum is a 3rd century Roman mithraeum that was discovered in Walbrook during construction work in 1954. The entire site was relocated several times before being returned to its original site as part of the new Bloomberg building. This temple of the mystery god Mithras became perhaps the most famous 20th-century Roman discovery in London. In addition to the temple structure, there is a display of Roman artefacts found on the site and a contemporary art exhibit responding to the site. Visitor numbers are limited and timed slots are often fully booked up several weeks into the future so plan well ahead.

This small tower across the road from the Houses of Parliament is the only part of the original Palace of Westminster still standing. While it is overshadowed in splendour by the surrounding buildings, it's well worth a visit, and has good displays about the early history of Westminster.

Park overlooking the river, with the local war memorial. Be careful at high tide, as it may flood.

The eastern half of the twin parks. Of the two, Hyde Park is open for longer and has more open, unwooded land; it is often host to concerts, fun fairs and events. More of an artificial stream than a fountain, flowing in an oval through an open grassy area which, in normal summers, is a popular paddling spot for children and grown-ups alike.
