Christ Church

Statue in honour of the World War I nursing heroine.

An enormous, 135-metre-high observation wheel with 32 exterior glass-walled capsules. It offers incomparable views over central London and up to 40 km (25 mi) away on a good day. Tickets are sold for specific times, so if visitors wish to go on the London Eye at a specific time, they are strongly advised to book in advance, particularly in the summer. On a busy day, you can easily spend 1-3 hr queuing just to buy a ticket. However, you can also purchase tickets in advance online. Then you can collect your tickets at the London Eye in a separate queue, which takes a few minutes or less.

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

Probably the most popular of all the museums here and a must see for many visitors to London. Home to at least 70 million specimens from across all the life sciences. It's difficult to say what the most popular exhibit here is; the blue whale which towers over the entrance hall, the (now slightly tacky-looking) animatronic Tyrannosaurus rex in the dinosaur gallery, or the life-size model blue whale in the mammals gallery. Also well worth a check are the Darwin Centre (book on a free tour to see some of the most interesting, and sometimes gruesome, specimens not on public display); and the studio dedicated to BBC wildlife personality extraordinaire, David Attenborough. The NHM's "Earth Galleries" were once the adjacent Geological Museum, an independent institution until the 1980s, and still located in a separate building with a separate entrance.

Eccentric Gothic home of 18th-century poet and author, Horace Walpole, son of England's first prime minister.

Beautiful Italianate church created during the Catholic revival of the 19th century.

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.

An enormous art gallery converted from the former Bankside Power Station, a visit to Tate Modern could easily take half a day. The gallery collects together contemporary and modern art from around the world, arranged thematically. The most stunning aspect of the building, is the enormous Turbine Hall, which plays host to a single piece of work commissioned for the space each year. An extension of the gallery has opened in a ten-storey building behind the existing power station.

The oldest church in the City, founded by Saxon abbots in 675 AD.

The ruins of a church dating back to Saxon times, rebuilt by St Dunstan in 950, destroyed in the Great Fire of London, and then rebuilt by Sir Christopher Wren in 1697. Most of the church was destroyed during the blitz, leaving only the tower (dating from Wren's time) and hollowed-out walls (from an 1817 reconstruction). The ruins are now overgrown with picturesque vines and trees, and were converted into a public garden in 1967, complete with benches.

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.

Founded in 1123, by jester-turned-monk Rahere, this Norman church is one of the oldest in London. It was damaged in the Dissolution but managed to escape both the Great Fire and the Blitz. This is a Grade I listed building. Tourists are welcome when services are not in progress and are charged an admission fee (which does not apply to those coming to pray or use the café).

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.
