Palace of Westminster

Constructed 1672-9 to a design by Sir Christopher Wren and regarded as one of the finest Wren churches. The 63 feet (19 m) high dome is based on Wren's original design for St Paul's Cathedral. The circular altar is by the British sculptor Henry Moore, and the kneelers are designed by Patrick Heron. Free lunchtime concerts at 1PM on Tuesdays (except August). Free Organ recitals at 12:30PM on Fridays. Occasional art exhibitions on Christian themes and other events.

Grade I listed Saxon church founded before the 12th century. The exterior was mostly constructed in the 15th century, and the interior in the 19th. The north side of the church houses a musician's chapel opened in 1955. In addition to the services, there are often evening (chargeable) concerts.

Dr Samuel Johnson was the highly distinguished 18th-century "man of letters", best known for his comprehensive English Dictionary of 1755, but also for his prolific output of poems, essays and novels. Something of a "hidden gem", this small, independent museum is dedicated to him—and, with its historic interiors, paintings and prints, personal effects and other exhibits—gives an impression of what it might have been like during his occupancy from 1748 to 1759. Built in 1700, this impressive period building—a rare example of its kind in the area—survived the brutal onslaught of the Blitz during World War II and is now maintained in excellent condition.

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.

A branch of the Imperial War Museum, the Cabinet War Rooms preserves the underground corridors and rooms from which Churchill and the cabinet directed the war against Hitler and the Nazis, maintained almost exactly as they were left in 1945. In 1984, IWM opened the rooms to the public for the first time. In 2005, the attached Churchill Museum was opened as the world's first permanent museum dedicated to the life and wartime achievements of Sir Winston Churchill. Audio guides are included in your admission. No cloakroom, no rucksacks, no suitcases. Café is open daily from 10am to 5pm. Hot food is served until 3pm.

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.

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.

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

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.

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

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.

Discover mementoes of the famous fictional detective. In reality, this was a lodging house used in the late 1800s and has three floors. The first floor contains Sherlock Holmes' study with Watson's desk, and has bullet holes spelling the initials VR (for Victoria Regina, Latin for Queen Victoria) much to the chagrin of the landlady Mrs. Hudson. Next to that is Holmes' bedroom with a rogues' gallery containing photographs of several notable Victorian-era murderers including Lizzy Bourdain. The remaining rooms upstairs have waxwork figures and artefacts referencing the novels, as well as their adaptations to stage and screen. Photography allowed, though filming requires permission. Prebooking is recommended to circumvent long queues.
