20 Fenchurch Street

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

Discover mementoes of the famous fictional detective. In reality, this was a lodging house used in the late 1800s and has three floors. The first floor contains Sherlock Holmes' study with Watson's desk, and has bullet holes spelling the initials VR (for Victoria Regina, Latin for Queen Victoria) much to the chagrin of the landlady Mrs. Hudson. Next to that is Holmes' bedroom with a rogues' gallery containing photographs of several notable Victorian-era murderers including Lizzy Bourdain. The remaining rooms upstairs have waxwork figures and artefacts referencing the novels, as well as their adaptations to stage and screen. Photography allowed, though filming requires permission. Prebooking is recommended to circumvent long queues.

After visiting the two Houses, visitors pass back through St. Stephen's Hall, and through Westminster Hall. Westminster Hall is one of the few areas of Parliament in which photography is permitted, and it is a very impressive place, dating back to the 9th century. Plaques on the floor mark where the bodies of deceased members of the royal family and other distinguished individuals granted the privilege by the British government lay in state (most recently Queen Elizabeth II in 2022), and significant events which took place in the hall (such as the trial of King Charles I).

One of the most expensive residential streets on the planet! Most of the buildings here are embassies or ambassadorial residences but the rest of the mansions belong to some of the richest people in the country (or elsewhere). For added historical value, during World War II, the current Norwegian embassy was where King Haakon VII led the Norwegian government-in-exile (commemorated by a blue plaque) and MI19's "London Cage" prisoner-of-war facility was located here. There is no public right of way but the Crown Estate allow pedestrians and cyclists to use the street; photography is not permitted.

More of an artificial stream than a fountain, flowing in an oval through an open grassy area which, in normal summers, is a popular paddling spot for children and grown-ups alike.

The most senior of the Royal palaces in London (built between 1531 and 1536) and the official seat of the monarch.

A 900-year-old tree stump carved and painted to feature elves and small animals.

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.

The National Portrait Gallery is just around the corner from the National Gallery and is an entertaining way to learn about British history since the Tudors. Visitors walk around the gallery chronologically, viewing portraits of notable figures from British history - from Henry VII, painted by Hans Holbein, to Blur, painted by Julian Opie.

As with any Merlin attraction, it is arguably overpriced for what it is. Brings to life the gorier elements of London's past both real life and fictional. Including the execution of Charles I after the English Civil War, the bubonic plague, Jack the Ripper, Mrs. Lovett's pie shop and Sweeney Todd's barber shop with faithful recreations of disaster, disease, and torture using live actors. Younger children may be scared.

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.

Designed by one of Britain's leading architects, Sir Norman Foster, this curved glass skyscraper was the 2004 recipient of the Stirling Architectural Prize for Best Building. It was built on the site of the Baltic Exchange building, destroyed in 1992 by an IRA bomb which killed three. On the Bury Street side of the Gherkin by some black stone benches is the Tomb of the Unknown Girl for a teenaged Londoner who died 1,600 years ago (see infobox above), marked with a marble laurel wreath and inscription. Searcy's Restaurant (from £50) at the top takes bookings up to five weeks in advance and you have to go through security before going up.

In many cities a local transport museum would be of very narrow interest - not London, however! London's public transport is iconic, and the story of how it developed from horse and cart through early buses, Tube trains and trolleybuses to the present day is well worth coming to find out about. There is plenty of opportunity to clamber aboard the historic buses and Tube trains on display. Also, because London's transport is so well known, the museum shop contains plenty of items that make interesting and original gifts and souvenirs.

An attractive Gothic Revival church, completed in 1859 to a design by William Butterfield.

Designed and built in 1619-1622 by the Neo-Classical architect Inigo Jones, The Banqueting House is now all that remains of Whitehall Palace, the sovereign's principal residence from 1530-1698 when most of it was destroyed by fire. Renowned for its architecture and paintings (by Rubens, among others), the building is also famous for being the scene of Charles I's execution in 1649 at the end of the English Civil War.

The Abbey charges tourists for entry, but not for worshippers. Attend a church service for free and enjoy some of the finest choral music in London from the choir. Choral Evensong at 3pm (Sa Su) or 5pm (weekdays), depending on time of year, is an especially good bet. The Abbey is the traditional scene for the coronation of British monarchs and the burial place of many past kings and queens. The Abbey contains a good gift shop and the Cellarium Café, which traces its history to the 14th century, is a good place to buy a noontime meal. Westminster Abbey is usually open to visitors from Monday to Saturday throughout the year. On Sundays and religious holidays such as Easter and Christmas, the Abbey is open for worship only. All are welcome and it is free to attend services. Visitor access to the Abbey is via the West Gate of the North Green.
