At the junction of five major roads, Piccadilly Circus is the home of the famous aluminum statue of Eros, which sits atop a fountain. The monument is officially known as Shaftesbury Memorial Fountain and initially wasn't supposed to depict Eros, but different god Anteros. The north side of Piccadilly Circus holds an enormous display board of electric advertisements, including Britain's biggest illuminated display (the widest in the world), advertising Coca-Cola.

Official residence of the Lord Mayor of the City of London, completed in 1753.

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.

A historic boat, part of the Imperial War Museum.

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.

On the UNESCO World Heritage List, the Palace of Westminster is the seat of Parliament in the United Kingdom. It's often termed the "Mother of All Parliaments" - an exaggeration, but perhaps only a slight one. The present building largely dates from the 19th century when it was rebuilt following a fire in a splendid example of Victorian neo-Gothic architecture. The House of Commons (elected Members of Parliament or MPs) is located to the north of the building and is decorated with green leather upholstery, and the House of Lords (unelected Lords) is located to the south and decorated with red leather upholstery.

This is probably the most famous criminal court in the world, and has been London's principal criminal court for centuries. It hears cases remitted to it from all over England and Wales as well as the Greater London area. The present building dates largely from 1907 (a new block was added from 1970 for more modern facilities) and stands on the site of the infamous medieval Newgate Gaol. The Central Criminal Court is of course best known today for its association with John Mortimer's Rumpole of the Bailey character, novels and television series. Daily case listings are available at The law pages. No bags, cameras, drinks, food or mobile phones—no facilities for safekeeping. Children under 14 are not admitted.

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.

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.

Museum at the former home of Dickens exhibiting writings, paintings, furniture and other items relating to the writer.

The ruins of a church dating back to Saxon times, rebuilt by St Dunstan in 950, destroyed in the Great Fire of London, and then rebuilt by Sir Christopher Wren in 1697. Most of the church was destroyed during the blitz, leaving only the tower (dating from Wren's time) and hollowed-out walls (from an 1817 reconstruction). The ruins are now overgrown with picturesque vines and trees, and were converted into a public garden in 1967, complete with benches.

A neoclassical triumphal arch, designed by Decimus Burton and first erected in 1826 as a grand entrance to Buckingham Palace. From 1846 onwards, the arch was topped with a massive equestrian statue of the Duke of Wellington - a major road widening of Piccadilly in 1882 was the opportunity to finally remove the over sized statue to Aldershot. The present magnificent statue Peace Descending on the Quadriga of War was placed on top of the Arch in 1912, and remains today the largest bronze sculpture in the United Kingdom, spectacularly lit at night. During the 1950s, the arch served as the smallest police station in the city, when it was occupied by ten constables, two sergeants and a cat! The arch was opened to the public for the first time in 2001 after a £1.5 million restoration by English Heritage. (Wellington Arch is also available for corporate and private events, with dramatic views down Constitution Hill and across central London from the Arch's spacious balconies, Wellington Arch is a novel and unique place to impress your guests).
