Downing Street

The oldest of the Royal Parks of London.

Islamic Cultural Centre and the main mosque in London. Visitors are welcome but must be suitably attired. The Mosque runs classes, prayers, talks and events.

At 87 hectares this is the largest open green space in the district.

This steel pedestrian bridge connecting Bankside with the City of London has all the lovely views of the Thames that you'd expect, but most of those who cross Millennium Bridge never notice its most distinctive feature. The bridge is dotted with hundreds of tiny paintings, so small that you'll probably miss them under your feet if you're not looking for them.

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.

The unusual "walkie scorchie" profile of this skyscraper by Rafael Vinoly has seen it grab the headlines, as did the "death rays" caused by the sun's heat reflecting off the building onto the street below when it was first completed; car tyres melted and burst, and at least one man fried an egg using only the heat from the walkie talkie. Visitors can access the sky garden to see a magnificent view over the City and beyond; it's the only place you can't see the tower from! Online booking to visit during the day is essential. Alternatively, you can eat at one of the restaurants in the evening.

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.

A neoclassical church that stands opposite the National Gallery. Since World War I, the homeless have sought shelter at this church, a tradition that continues to this day.

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.

Founded by veteran designer Zandra Rhodes.

A modest museum covering local history which relocated in 2010; has an excellent cafe.

A vast repository of the world's cultures, controversially including hundreds of items that were looted from their places of origin. Entire sections are devoted to Egyptian, Greek, and Middle Eastern artifacts, as well as the piece which united them all, the Rosetta Stone. Other items on everyone's list are the largest collection of mummies outside Egypt and the Elgin Marbles. The collection also includes some of the world's finest collections of Chinese and Sub-Saharan African art; perhaps the most famous of the latter are the Benin bronzes. A definite highlight of a trip to London. Temporary exhibitions are invariably excellent and meticulously researched, but can be expensive. It has a fine store, mainly selling replicas of items in the collection.

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

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.
