Marble Hill House

The great domed cathedral of St Paul's, designed by Sir Christopher Wren to replace the Gothic medieval cathedral destroyed in 1666 in the Great Fire of London, was built between 1675–1710. Of the most famous London sights, St Paul's is the one most conveniently located for the Barbican. It's a significant building in British history, having been the site of the funerals of several British military leaders (Nelson, Wellington, Churchill), and significantly held peace services marking the end of the two world wars. The cathedral is also famous for its Whispering Wall, as well as its stunning view over the city. The crypt is also open to the public, holding the tombs of Nelson, Wellington and Christopher Wren. It is possible to sidestep the admission charge by entering for one of the midday services, even if you don't take part, or for the daily choral evensong in the late afternoon. However, you'd still need a ticket to get to the top. Photography is not allowed.

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.

The eastern half of the twin parks. Of the two, Hyde Park is open for longer and has more open, unwooded land; it is often host to concerts, fun fairs and events. 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.

Designed by Sir Christopher Wren, this tall column (which can be ascended to get a great view) marks the alleged site where the Great Fire of London broke out in September 1666.

An enormous art gallery converted from the former Bankside Power Station, a visit to Tate Modern could easily take half a day. The gallery collects together contemporary and modern art from around the world, arranged thematically. The most stunning aspect of the building, is the enormous Turbine Hall, which plays host to a single piece of work commissioned for the space each year. An extension of the gallery has opened in a ten-storey building behind the existing power station.

Su Catholic Church of England with bells and smells (incense). There is an impressive model of the old London Bridge.

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

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.

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

This park used to be the grounds of Lambeth Palace but has been a public park since 1901. In addition to the green space it provides, it contains a range of sports facilities (booking required, except for the cricket nets) and a playground.

A private residence which can only be seen from the street. Designed and built in a French neo-Gothic style by William Burges, it features a handsome cone-roofed tower. Legendary guitarist Jimmy Page has been the house's proud owner since he bought it from actor Richard Harris in 1972.

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

This small tower across the road from the Houses of Parliament is the only part of the original Palace of Westminster still standing. While it is overshadowed in splendour by the surrounding buildings, it's well worth a visit, and has good displays about the early history of Westminster.

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.

There are three notable outdoor bathing ponds on the heath. The Men's Pond and Women's Pond are both part of the line of small lakes on the eastern edge of the heath known as Highgate Ponds, and the Mixed Pond is part of Hampstead Ponds on the opposite side. Swimming hours are seasonal, complicated, age-dependent and change frequently, so it is worth checking before making a special trip.
