The studio is quite visible from the plaza outside and some parts of the show are performed from outside of the studio – in the plaza.

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.

This garden square was established by Lord Southampton in 1665 and is the oldest square in London. It was opened to the public in the 1950s. The square is surrounded by a number of beautiful 18th- and 19th-century buildings and terraces.

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.

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.

A small realm of serenity in the midst of the typical turmoil. It used to be the court of the Knights Templar. You can still visit the beautiful Romanesque church, which is one of the oldest ones in London (opened in 1185) and has connections to the order of Templars. The chancel of the church was built by Henry III. The church still serves the members of Gray's Inn and Lincoln's Inn and has frequent services open to the public. Fans of Dan Brown's The Da Vinci Code will recognise the church from both the novel and the film.

Beautiful Italianate church created during the Catholic revival of the 19th century.

A royal residence which is still used by Prince William, Kate and their young family. Much of it is however open to the public and it is a very popular tourist attraction perhaps due as much to its association with Princess Diana as anything else. The King's Gallery here is a magnificent Regency period court drawing room and contains some impressive paintings including a Van Dyke. Also a nice restaurant on site called The Orangery.

The headquarters of world's most famous insurance market, housed in a revolutionary (at the time) bizarre, Matrix-like glass-and-steel building designed by Richard Rogers, with all support services (lifts, ventilation, etc.) suspended outside. Recognised as a masterpiece of exoskeleton architecture.

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.

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.

This park used to be the grounds of Lambeth Palace but has been a public park since 1901. In addition to the green space it provides, it contains a range of sports facilities (booking required, except for the cricket nets) and a playground.

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.

Former offices of the Greater London Authority. A radically-designed glass fronted and rounded building, previously headquarters for London's Mayor and Assembly. City Hall has now be relocated to The Crystal, a building in Greenwich, near to the cable car. The old building is disused and not open to the public, but can be viewed from the outside.
