Barbican Conservatory

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).

Now preserved by the National Trust, this 18th-century house was the home of the historian Thomas Carlyle from 1834 and now houses a museum dedicated to his life and work.

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.

Magnificent 19th-century bridge, decorated with high towers and featuring a drawbridge. The bridge opens several times each day to permit ships to pass through – timings are dependent on demand, and are not regularly scheduled. When Tower Bridge was built, the area to the west of it was a bustling port – necessitating a bridge that could permit tall boats to pass. Now the South Bank area sits to its west, and the regenerated Butler's Wharf area of shops and riverside restaurants lie to its east. You can get the lift to the top level of the bridge and admire the view. Glass floors provide an interesting perspective for the brave. The museum highlights the bridge's history and engineering, and there are photographic exhibitions along the walkways between the towers.

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

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.

At 87 hectares this is the largest open green space in the district.

Statue in honour of the World War I nursing heroine.

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

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.

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.

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.

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.

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.
