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.

Medieval Grade I listed church. This church played a key role in the English Revolution and was the parish church of some of the most decisive Puritans: Oliver Cromwell was married and this is where John Milton was buried. It was the home of the Morning Exercises. The tower remains from the original building; the rest was destroyed in the Blitz but rebuilt based on the original plans.

This venerable old institution was absorbed by the neighbouring Natural History Museum in 1985 but still has something of a separate identity. Unsurprisingly, devoted to all things geological with especially popular exhibits on vulcanology and earthquakes and fossils of all types. Very popular with kids and often underrated.

Art deco headquarters of University of London featured in the film Nineteen Eighty-Four.

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.

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.

An intersection of seven streets in the northern part of the Covent Garden district. Lots of mid-range designer clothing and shoe stores

The Abbey charges tourists for entry, but not for worshippers. Attend a church service for free and enjoy some of the finest choral music in London from the choir. Choral Evensong at 3pm (Sa Su) or 5pm (weekdays), depending on time of year, is an especially good bet. The Abbey is the traditional scene for the coronation of British monarchs and the burial place of many past kings and queens. The Abbey contains a good gift shop and the Cellarium Café, which traces its history to the 14th century, is a good place to buy a noontime meal. Westminster Abbey is usually open to visitors from Monday to Saturday throughout the year. On Sundays and religious holidays such as Easter and Christmas, the Abbey is open for worship only. All are welcome and it is free to attend services. Visitor access to the Abbey is via the West Gate of the North Green.

The restoration of the nave was completed in September 2004, and this church is still a striking building designed by Sir Nicholas Hawksmoor with a particularly tall, pointed spire. Hawksmoor's design was significantly altered in the 19th century, and present continuing restoration is intended to restore it to Hawksmoor's original vision. Christ Church was built as part of the 50 Churches for London project.

A memorial made out of 52 stainless steel columns representing each of the 52 victims who died in a series of terrorist attacks in the London bombings on July 7th, 2005.

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.

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.

Originally the private garden of Holland House, much of which was destroyed in the London Blitz, Holland Park is a mixture of woodland, European and Japanese-style formal gardens and leisure facilities. It includes a large field dedicated to football and cricket, as well as tennis courts. As you walk around the park, you can see bits of the house dotted around the place which give you some idea of how grand it used to be. In the summer this is a great place to catch outdoor opera. An ecology centre near the police station provides information about the ecology of the park and arranges various activities for children. There is a café in the park that sells ice creams and hot food. The park is a popular way to walk from Notting Hill to Kensington High Street.

Created by Tonkin Zulaikha Greer and Janet Laurence to remember the Australians who died in both world wars. Made from Australian granite.

The second biggest greenhouse in London, containing over 2,000 species of tropical plants as well as birds and fish.

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.
