Highgate Cemetery

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.

Formerly the teaching collection of Sir Flinders Petrie, one of Britain's greatest archaeologists, now preserved by University College London. Exhibits include beaded dresses, sculpture and wall reliefs, items of everyday use, papyri, cartonnage and pottery. Fascinating!

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.

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.

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.

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.

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.

Substantial nature reserve on the old disused Barn Elms Reservoirs. A major wetland habitat for wintering wildfowl and an excellent choice for any keen birders visiting London, and an entertaining place for kids to learn about nature

An intersection of seven streets in the northern part of the Covent Garden district. Lots of mid-range designer clothing and shoe stores

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.

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).

Three large auditoriums, the Olivier, the Lyttelton and the Cottesloe. The Olivier theatre is the largest with an open stage and a fan shaped auditorium around it. This ensures that all seats provide a good view. Most of the more 'popular' productions are put on here as the space provided is much larger than most theatres. The Lyttelton theatre is more traditional with a proscenium arc with good views from most seats. The Cottesloe is a small studio theatre, seating around 400. Some tickets will be available on the day, either day seats (arrive before 9:30AM and queue) or standby (arrive before 6PM and queue), or you can buy online. Popular shows, especially those around Christmas in the Olivier sell out months in advance. Tickets to The National Theatre are generally better value than most other theatres. There is also the '£15 Travelex' season in the summer (as of 2019) that provides a large number (over 100,000 seats a year) at £10. Booking in advance is required for these. There is also an exhibition space in the Lyttelton theatre foyer that frequently holds popular photographic exhibitions. Free jazz is often played in the evening in the ground floor foyer. During summer there is a free daily outdoor festival of performance, music, comedy and cabaret known as Watch This Space. Deckchairs (and artificial grass) are provided to watch on. Free exhibitions. Backstage tours £5.

The Serpentine is a long, thin artificial lake within Hyde Park which contains a range of waterfowl and fish. It was first made by damming the River Westbourne but it is now fed by three boreholes. The western end of the lake is actually in Kensington Gardens, in which it is called The Long Water. Swimming and boating are popular activities on the Serpentine; see 'Do' section.

Constructed 1672-9 to a design by Sir Christopher Wren and regarded as one of the finest Wren churches. The 63 feet (19 m) high dome is based on Wren's original design for St Paul's Cathedral. The circular altar is by the British sculptor Henry Moore, and the kneelers are designed by Patrick Heron. Free lunchtime concerts at 1PM on Tuesdays (except August). Free Organ recitals at 12:30PM on Fridays. Occasional art exhibitions on Christian themes and other events.

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.

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

After leaving its brutalist skyscraper on Old Broad St, the London Stock Exchange now resides on Paternoster Sq. Dating back to 1698, it is one of the world's oldest and largest stock markets.
