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

A neoclassical triumphal arch, designed by Decimus Burton and first erected in 1826 as a grand entrance to Buckingham Palace. From 1846 onwards, the arch was topped with a massive equestrian statue of the Duke of Wellington - a major road widening of Piccadilly in 1882 was the opportunity to finally remove the over sized statue to Aldershot. The present magnificent statue Peace Descending on the Quadriga of War was placed on top of the Arch in 1912, and remains today the largest bronze sculpture in the United Kingdom, spectacularly lit at night. During the 1950s, the arch served as the smallest police station in the city, when it was occupied by ten constables, two sergeants and a cat! The arch was opened to the public for the first time in 2001 after a £1.5 million restoration by English Heritage. (Wellington Arch is also available for corporate and private events, with dramatic views down Constitution Hill and across central London from the Arch's spacious balconies, Wellington Arch is a novel and unique place to impress your guests).

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.

Completed in 1633 to a design by Inigo Jones.

The restoration of the nave was completed in September 2004, and this church is still a striking building designed by Sir Nicholas Hawksmoor with a particularly tall, pointed spire. Hawksmoor's design was significantly altered in the 19th century, and present continuing restoration is intended to restore it to Hawksmoor's original vision. Christ Church was built as part of the 50 Churches for London project.

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.

Official residence of the Lord Mayor of the City of London, completed in 1753.

191-m (627-ft) skyscraper can be seen from far away and is the sixth highest building in UK.

A royal residence which is still used by Prince William, Kate and their young family. Much of it is however open to the public and it is a very popular tourist attraction perhaps due as much to its association with Princess Diana as anything else. The King's Gallery here is a magnificent Regency period court drawing room and contains some impressive paintings including a Van Dyke. Also a nice restaurant on site called The Orangery.

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.

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.

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 remains of the once-magnificent palace, home to English kings since Edward I, adjoin Richmond Green, a pleasant open green space and historic cricket ground. Only the Gate House and Wardrobe, now converted into flats, remain.

St. Margaret's is the church of the British Parliament, more specifically, the parish church of the House of Commons.

Garden founded by apothecaries in the 17th century to the medicinal properties of plants. It was only opened to the public in the 1980s, when it became a charity. The heat-sink caused by its thick walls, combined with the general waste heat of London itself, keeps the garden much warmer than it would otherwise be at this latitude. Due to this, the garden contains the world's most northerly example of a grapefruit outside of a greenhouse, and the largest fruiting olive tree in the country. The collection contains thousands of different plant species.
