Cabinet War Rooms and Churchill Museum

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.

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.

Church in Piccadilly designed by Sir Christopher Wren in 1684. It has a magnificent organ case and baptismal font by Grinling Gibbons.

The TfL-backed Hidden London offers tours around the disused Aldwych tube station which had its own branch on the Piccadilly line. The tour explains the station's unusual history including its use for protection (for both people and historical artefacts held by the British Museum) from the Blitz during WWII. More recently, it was used as a filming location and for testing station equipment and decor. Of note, it was used for filming James Bond: Die Another Day, V for Vendetta and the Prodigy music video for Firestarter. Tours are roughly an 1 hour and 15 minutes long, wear sturdy shoes (not sandals).

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.

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 Duke and Duchess of Lauderdale's elegant 17th-century manor house, a mile or so upriver from Richmond riverside.

Peaceful gardens and interesting monuments including the daughter of Richard Cromwell, son of Oliver Cromwell.

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.

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.

Historic home to English kings such as Henry VIII, now open to the public. There are many attractions which can occupy a whole day visit, including 60 acres of gardens with the famous maze, the Tudor kitchens, the Chapel Royal, the Great Hall, Mantegna's Triumphs of Caesar paintings, and various exhibitions about Henry VIII.

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.

The former home of Sigmund Freud. A wide range of exhibits, most famously including the psycho-analytic couch that all of his patients used. Freud was an avid collector of antiquities and there is a fine collection of Greek, Roman and Oriental pieces on show.

One of the oldest churches in Battersea, this church is where Christians have worshiped at the same site since 800 AD. It is protected as a Grade I listed building with its combination of heritage and architectural merit.

Cleopatra's Needle originated in the ancient Egyptian city of Heliopolis, in the Temple of Atum, but the Romans moved it to Alexandria in 12 BC. In 1819, viceroy Mehemet Ali presented Cleopatra's Needle to the British, commemorating military victories in Egypt, but it remained in Alexandria until 1877 when transportation was arranged to bring it to London. On the voyage, the ship capsized in a storm, killing six crewmembers. Cleopatra's Needle was thought to be lost, but Spanish trawlers found it afloat a few days later, and after some repairs, it arrived in London on 21 Jan 1878. The obelisk is flanked by two faux-sphinxes, which show the effects of bombings of London during World War II. Today, Cleopatra's Needle shows some wear from exposure to London's damp weather.
