St Paul's Cathedral

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.

The largest square in London. It was established in 1806 by the 5th Duke of Bedford and his statue can still be seen in the square. There is also a café.

The main residence of His Majesty King Charles III, Her Royal Highness Queen Camilla, and latterly of HM Queen Elizabeth II. In the summer, 19 State Rooms are open to the public. Places are strictly limited, and it might not be possible to just turn up and get a ticket for a specific entry time, visitors should book in advance to ensure admission.

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).

The oldest of the Royal Parks of London.

Completed in 1633 to a design by Inigo Jones.

Dedicated to scientific exhibitions and collections bar those related to the life sciences. A number of famous historical machines and inventions are housed here, from steam locomotives to the Apollo 10 command module. The space exhibits are especially popular. Exhibitions tend to concentrate on explaining scientific principles with working models and there is a strong emphasis on education and attracting children. The Science Museum opened a "Children's Gallery" in the 1930s and it continues to lead the way in this area; now, there are three separate galleries aimed at all ages of younger visitor, from 5 to 16. The museum also runs "Science Nights" whereby children spend an evening learning principles and participating in experiments before spending the night sleeping in the museum with the exhibits. Also houses a vast library of scientific and medical books and journals.

A small realm of serenity in the midst of the typical turmoil. It used to be the court of the Knights Templar. You can still visit the beautiful Romanesque church, which is one of the oldest ones in London (opened in 1185) and has connections to the order of Templars. The chancel of the church was built by Henry III. The church still serves the members of Gray's Inn and Lincoln's Inn and has frequent services open to the public. Fans of Dan Brown's The Da Vinci Code will recognise the church from both the novel and the film.

Prestigious contemporary art gallery worth a visit.

The Royal Academy no longer has a permanent exhibition space, instead hosting art exhibitions. Notable exhibitions have included the paintings of Monet, contemporary art associated with the theme of apocalypse, and Aztec art. Each Summer, the Royal Academy plays host to a Summer Exhibition, displaying 1,200 new works by established and new artists selected by the academy, most of which are available for visitors to buy. Each member has to donate a work of art, so over the years, the academy has built a sizable collection. Exhibitions are invariably excellent, and it is worth paying for audio guides, if they are not included. Visitors should book tickets in advance, as exhibitions are often very popular – particularly shortly after opening.

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.

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.

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 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.

One of the "Magnificent Seven" old cemeteries in London. Graves range from plain to ornate and the site can be a tranquil place to walk amid the bustle of the city. It was opened in 1840 and is still a working cemetery, although it was closed for some time in the late 20th century. Can be nice, if morbid, for an afternoon stroll, especially as a route (and cycle route) between Old Brompton Road and Fulham Road.

This church on the bank of the Thames was built in 1157. It is the only church in London with chained books. A statue of Thomas More sits in front of the church.

Church in Piccadilly designed by Sir Christopher Wren in 1684. It has a magnificent organ case and baptismal font by Grinling Gibbons.
