Buckingham Palace

The world's main marketplace for ship broking.

Probably the most colourful event in the UK's legislative calendar, this takes place in May or June every year, or after a general election, when the King travels to the Houses of Parliament to open the new parliamentary session. During this event, the Lords, Speaker of the House of Commons, and other office holders can be seen dressed in their ceremonial robes, and there is always an elaborate procession when the King makes his way to the Houses of Parliament from Buckingham Palace. This is one of the few occasions where all branches of the British government are gathered in the same place. Many traditions of the State Opening can trace their origins to a more turbulent past, when the relationship between the monarch and Parliament was sometimes antagonistic. In particular, since the English Civil War, the monarch has been banned from entering the House of Commons chamber, and instead must send a representative (the Black Rod) to summon the MPs to the Lords chamber, where he delivers his speech. Another notable tradition is the holding of a Hostage MP in Buckingham Palace, ostensibly to guarantee the safe return of the monarch, who is released once the King has returned to the palace safely after delivering his speech. While attendance at Parliament itself is limited to special guests that have been invited by the Prime Minister, it is broadcast live on the BBC, and you can also view the King's procession from Buckingham Palace to Parliament from the roadside for free.

The London Mithraeum is a 3rd century Roman mithraeum that was discovered in Walbrook during construction work in 1954. The entire site was relocated several times before being returned to its original site as part of the new Bloomberg building. This temple of the mystery god Mithras became perhaps the most famous 20th-century Roman discovery in London. In addition to the temple structure, there is a display of Roman artefacts found on the site and a contemporary art exhibit responding to the site. Visitor numbers are limited and timed slots are often fully booked up several weeks into the future so plan well ahead.

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.

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

Substantial nature reserve on the old disused Barn Elms Reservoirs. A major wetland habitat for wintering wildfowl and an excellent choice for any keen birders visiting London, and an entertaining place for kids to learn about nature

Large open space very popular with Londoners and less visited by tourists than the other great city parks. A number of lovely lakes, an open air theatre, regular puppet shows, various sporting activities and some splendid ancient trees. There is also a cafe and play area next to the boating pond. London's main zoo is in the northern reaches of Regent's Park. Takes a very conservation-driven approach these days and always has great exhibits aimed at children. Opened in 1828 for scientific study, then to the public in 1847. 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.

This gallery houses the Tate collection of British art from 1500 through to contemporary art. A side wing collects together the gallery's collection of paintings by Turner, including some stunning seascapes. Temporary exhibitions are exceedingly varied: examples include exhibitions of Turner's paintings of Venice and the work of photographer Wolfgang Tillmans. The best known exhibition is the Turner Prize, consists of works by four artists shortlisted for the annual contemporary art prize, which runs from late October to January each year.

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.

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 Victorian school, now a university with a mission to advance knowledge of the fine arts. Exhibitions are common. Times and admission charges vary but can often be free, although visitors may need to book tickets to certain events.

This church on the bank of the Thames was built in 1157. It is the only church in London with chained books. A statue of Thomas More sits in front of the church.

Equestrian statue of the Iron Duke, with four soldiers at each corner of the pedestal, representing regiments that fought under him: a Grenadier, Scottish Highlander, Irish Dragoon, and Welsh Fusilier. The bronze came from melting down captured French cannons.

On the UNESCO World Heritage List, the Palace of Westminster is the seat of Parliament in the United Kingdom. It's often termed the "Mother of All Parliaments" - an exaggeration, but perhaps only a slight one. The present building largely dates from the 19th century when it was rebuilt following a fire in a splendid example of Victorian neo-Gothic architecture. The House of Commons (elected Members of Parliament or MPs) is located to the north of the building and is decorated with green leather upholstery, and the House of Lords (unelected Lords) is located to the south and decorated with red leather upholstery.

The London residence of the Dukes of Wellington, which now acts as a museum for the inaugural and most famous holder of the title. It boasts an impressive collection of paintings, sculptures, medals and swords. Perhaps the most bizarre item in Wellington's collection is a nude statue of Napoleon Bonaparte, commissioned by the emperor himself and bought by the British government following his defeat at the Battle of Waterloo as a gift for the duke.
