Royal College of Music

Site of the London residences for the Prime Minister (No. 10) and the Chancellor (No. 11).

A medieval church that was rebuilt in the late 18th century, noted for its well-preserved interior. The former churchyard was converted into a public space in 1880, called Postman's Park as it was frequented by workers from the nearby Post Office headquarters.

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.

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

Founded by veteran designer Zandra Rhodes.

A treasure trove of antique toys exhibited in a warren of 6 rooms above the toy shop of the same name. A very charming place indeed, though the doll rooms are a bit gruesome.

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.

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

A lovely park on the southern banks of the Thames known or its wildlife and some splendid examples of mature trees.

A vast repository of the world's cultures, controversially including hundreds of items that were looted from their places of origin. Entire sections are devoted to Egyptian, Greek, and Middle Eastern artifacts, as well as the piece which united them all, the Rosetta Stone. Other items on everyone's list are the largest collection of mummies outside Egypt and the Elgin Marbles. The collection also includes some of the world's finest collections of Chinese and Sub-Saharan African art; perhaps the most famous of the latter are the Benin bronzes. A definite highlight of a trip to London. Temporary exhibitions are invariably excellent and meticulously researched, but can be expensive. It has a fine store, mainly selling replicas of items in the collection.

Remains of the wall that surrounded the City of London for almost two thousand years. The parts around the Barbican are mostly Tudor due to maintenance (Roman remains can be seen in and around the Tower of London). Other local remains are the 51.5169-0.095833 Noble St wall fragment and the 51.5177-0.092234 St Alphage Gdns wall fragment.

This is a high part of the Heath with clear open vistas, and the views looking south over the city are quite wonderful. Highly recommended on a clear morning, when you can see from Canary Wharf in the east all the way to Battersea Power Station in the west.

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.

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

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.
