St Margaret Pattens

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.

Magnificent 19th-century bridge, decorated with high towers and featuring a drawbridge. The bridge opens several times each day to permit ships to pass through – timings are dependent on demand, and are not regularly scheduled. When Tower Bridge was built, the area to the west of it was a bustling port – necessitating a bridge that could permit tall boats to pass. Now the South Bank area sits to its west, and the regenerated Butler's Wharf area of shops and riverside restaurants lie to its east. You can get the lift to the top level of the bridge and admire the view. Glass floors provide an interesting perspective for the brave. The museum highlights the bridge's history and engineering, and there are photographic exhibitions along the walkways between the towers.

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

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.

St. Margaret's is the church of the British Parliament, more specifically, the parish church of the House of Commons.

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.

A vast shopping, eating, entertainment and (primarily) business complex, home to Britain's second tallest skyscraper, One Canada Square. Now increasingly lively at weekends as well, but still at its most impressive during the week. Spectacular main exit from the Jubilee line Tube station. There is a substantial amount of information about the history and the architecture of the development on the website of Canary Wharf Group, the company that owns the development.

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

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.

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.

Dedicated to scientific exhibitions and collections bar those related to the life sciences. A number of famous historical machines and inventions are housed here, from steam locomotives to the Apollo 10 command module. The space exhibits are especially popular. Exhibitions tend to concentrate on explaining scientific principles with working models and there is a strong emphasis on education and attracting children. The Science Museum opened a "Children's Gallery" in the 1930s and it continues to lead the way in this area; now, there are three separate galleries aimed at all ages of younger visitor, from 5 to 16. The museum also runs "Science Nights" whereby children spend an evening learning principles and participating in experiments before spending the night sleeping in the museum with the exhibits. Also houses a vast library of scientific and medical books and journals.
