House of Commons Strangers' Gallery

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.

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

Fine stone bridge linking Twickenham/St Margarets with Richmond. It is the oldest surviving Thames bridge in London, dating from 1777.

Official residence of the Lord Mayor of the City of London, completed in 1753.

Old train station with an enormous office and shopping complex in glass and pale stone. A lavish hotel is also on the site. The name comes from the Queen Eleanor (13th century) gothic pillar outside the station, which is actually a Victorian-era replica. Charing Cross Road was once famous for its vintage book shops, but these have now largely disappeared due to high rents and online competition; however, the road is still home to one of London's largest bookshops, Foyle's.

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 royal residence which is still used by Prince William, Kate and their young family. Much of it is however open to the public and it is a very popular tourist attraction perhaps due as much to its association with Princess Diana as anything else. The King's Gallery here is a magnificent Regency period court drawing room and contains some impressive paintings including a Van Dyke. Also a nice restaurant on site called The Orangery.

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.

An attractive Gothic Revival church, completed in 1859 to a design by William Butterfield.

Built of Portland stone and dedicated to the aircrews of Allied nations under Bomber Command during World War II.

One of the most expensive residential streets on the planet! Most of the buildings here are embassies or ambassadorial residences but the rest of the mansions belong to some of the richest people in the country (or elsewhere). For added historical value, during World War II, the current Norwegian embassy was where King Haakon VII led the Norwegian government-in-exile (commemorated by a blue plaque) and MI19's "London Cage" prisoner-of-war facility was located here. There is no public right of way but the Crown Estate allow pedestrians and cyclists to use the street; photography is not permitted.

Historic home to English kings such as Henry VIII, now open to the public. There are many attractions which can occupy a whole day visit, including 60 acres of gardens with the famous maze, the Tudor kitchens, the Chapel Royal, the Great Hall, Mantegna's Triumphs of Caesar paintings, and various exhibitions about Henry VIII.

The headquarters of world's most famous insurance market, housed in a revolutionary (at the time) bizarre, Matrix-like glass-and-steel building designed by Richard Rogers, with all support services (lifts, ventilation, etc.) suspended outside. Recognised as a masterpiece of exoskeleton architecture.

Designed by Sir Christopher Wren, this tall column (which can be ascended to get a great view) marks the alleged site where the Great Fire of London broke out in September 1666.

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.

Dr Samuel Johnson was the highly distinguished 18th-century "man of letters", best known for his comprehensive English Dictionary of 1755, but also for his prolific output of poems, essays and novels. Something of a "hidden gem", this small, independent museum is dedicated to him—and, with its historic interiors, paintings and prints, personal effects and other exhibits—gives an impression of what it might have been like during his occupancy from 1748 to 1759. Built in 1700, this impressive period building—a rare example of its kind in the area—survived the brutal onslaught of the Blitz during World War II and is now maintained in excellent condition.

A small museum is set in a Victorian house near the infamous Battle of Cable Street. There are 5 floors including the basement, each dedicated to several aspects of famous murders starting with a recreation of Mitre Square on the first floor, Jack the Ripper's sitting room on the second floor, the police station on the third, a victim's bedroom on the fourth and the mortuary in the basement. There is also a walking tour. Book tickets online to save money, there is also a Halloween special deal.
