Tower of London

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 TfL-backed Hidden London offers tours around the disused Aldwych tube station which had its own branch on the Piccadilly line. The tour explains the station's unusual history including its use for protection (for both people and historical artefacts held by the British Museum) from the Blitz during WWII. More recently, it was used as a filming location and for testing station equipment and decor. Of note, it was used for filming James Bond: Die Another Day, V for Vendetta and the Prodigy music video for Firestarter. Tours are roughly an 1 hour and 15 minutes long, wear sturdy shoes (not sandals).

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.

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.

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.

The Royal Academy no longer has a permanent exhibition space, instead hosting art exhibitions. Notable exhibitions have included the paintings of Monet, contemporary art associated with the theme of apocalypse, and Aztec art. Each Summer, the Royal Academy plays host to a Summer Exhibition, displaying 1,200 new works by established and new artists selected by the academy, most of which are available for visitors to buy. Each member has to donate a work of art, so over the years, the academy has built a sizable collection. Exhibitions are invariably excellent, and it is worth paying for audio guides, if they are not included. Visitors should book tickets in advance, as exhibitions are often very popular – particularly shortly after opening.

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.

The world's main marketplace for ship broking.

The most senior of the Royal palaces in London (built between 1531 and 1536) and the official seat of the monarch.

A lovely park on the southern banks of the Thames known or its wildlife and some splendid examples of mature trees.

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

Not as popular with tourists as St Paul's north of the river, Southwark Cathedral has been the site of worship since the year 852. Literally in the shadow of London Bridge, the Cathedral is a shelter from the noise of the city. Next to the Cathedral is the Borough Market open Th-Sa with a wide range of speciality food to buy, a good area for lunch.
