New Zealand Memorial

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.

A small museum is set in a Victorian house near the infamous Battle of Cable Street. There are 5 floors including the basement, each dedicated to several aspects of famous murders starting with a recreation of Mitre Square on the first floor, Jack the Ripper's sitting room on the second floor, the police station on the third, a victim's bedroom on the fourth and the mortuary in the basement. There is also a walking tour. Book tickets online to save money, there is also a Halloween special deal.

A retirement home for soldiers created by King Charles II. Tours around the listed building and grounds are regular and include the museum (which can be visited separately) whose exhibits contain military memorabilia donated by Chelsea Pensioners over the years.

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).

Founded by William the Conqueror in 1066, enlarged and modified by successive sovereigns, the Tower is today one of the world's most famous and spectacular fortresses and a UNESCO World Heritage Site. Discover its 900-year history as a royal palace and fortress, prison and place of execution, mint, arsenal, menagerie and jewel house. In the winter you can skate on the dry moat. The Tower contains enough buildings and exhibits to keep a family busy for a full day, with plenty of both warlike and domestic contents. Some areas, such as the St John's Chapel in the White Tower, do not allow photography, but these are clearly signposted. Beefeaters, who are all retired sergeant majors from the British Army, provide guided tours for free as well as ceremonial security. See history come alive – go to the Ceremony of the Keys at the Tower of London. This ceremony, the locking up of the Tower, has been performed every night at 10PM for 800 years. Tickets for the ceremony are £5 and must be prebooked.

The oldest of the Royal Parks of London.

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.

Madame Tussauds is a world-famous waxwork museum, best known for its Grand Hall, with a collection of international royalty, statesmen and world leaders. Visitors generally report that the entrance fee does not warrant the selection of waxworks on show, which rarely resemble celebrities. Also, there is usually a long queue stretching down the road.

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.

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

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.

Founded in 1123, by jester-turned-monk Rahere, this Norman church is one of the oldest in London. It was damaged in the Dissolution but managed to escape both the Great Fire and the Blitz. This is a Grade I listed building. Tourists are welcome when services are not in progress and are charged an admission fee (which does not apply to those coming to pray or use the café).

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.
