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.

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.

A medieval church that was rebuilt in the late 18th century, noted for its well-preserved interior. The former churchyard was converted into a public space in 1880, called Postman's Park as it was frequented by workers from the nearby Post Office headquarters.

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

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

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.

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 remains of the once-magnificent palace, home to English kings since Edward I, adjoin Richmond Green, a pleasant open green space and historic cricket ground. Only the Gate House and Wardrobe, now converted into flats, remain.

Su Catholic Church of England with bells and smells (incense). There is an impressive model of the old London Bridge.

Designed by one of Britain's leading architects, Sir Norman Foster, this curved glass skyscraper was the 2004 recipient of the Stirling Architectural Prize for Best Building. It was built on the site of the Baltic Exchange building, destroyed in 1992 by an IRA bomb which killed three. On the Bury Street side of the Gherkin by some black stone benches is the Tomb of the Unknown Girl for a teenaged Londoner who died 1,600 years ago (see infobox above), marked with a marble laurel wreath and inscription. Searcy's Restaurant (from £50) at the top takes bookings up to five weeks in advance and you have to go through security before going up.

Home to the baroque composer George Frideric Handel from 1723 until his death in 1759. Some of the greatest classical music ever composed was done so at this address. The museum charts Handel's life and works and offers recitals of music in the magnificent setting of the period rooms. By contrast, next door was home to Jimi Hendrix when he lived in London in 1969, and entry to this top-floor flat is included.

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.

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