All Saints, Margaret Street

A treasure trove of antique toys exhibited in a warren of 6 rooms above the toy shop of the same name. A very charming place indeed, though the doll rooms are a bit gruesome.

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.

All non-classified government documents can be read and photographed here, with a (free) reader's card having been obtained. There is also a small museum, which does not require the card to access.

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.

Dr Samuel Johnson was the highly distinguished 18th-century "man of letters", best known for his comprehensive English Dictionary of 1755, but also for his prolific output of poems, essays and novels. Something of a "hidden gem", this small, independent museum is dedicated to him—and, with its historic interiors, paintings and prints, personal effects and other exhibits—gives an impression of what it might have been like during his occupancy from 1748 to 1759. Built in 1700, this impressive period building—a rare example of its kind in the area—survived the brutal onslaught of the Blitz during World War II and is now maintained in excellent condition.

The former home of Sigmund Freud. A wide range of exhibits, most famously including the psycho-analytic couch that all of his patients used. Freud was an avid collector of antiquities and there is a fine collection of Greek, Roman and Oriental pieces on show.

The world's main marketplace for ship broking.

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 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.

The Wallace Collection is one of the world's finest private art collections, the best known of which is Frans Hals's work The Laughing Cavalier. Other artists on display include Rembrandt, Titian, Poussin, and Reynolds. This is well worth escaping to after the hustle and bustle of Oxford Street.

Built of Portland stone and dedicated to the aircrews of Allied nations under Bomber Command during World War II.

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

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.

Statue in honour of the World War I nursing heroine.

The main, central square of London, Trafalgar Square is associated with celebration and demonstration - it is the site of London's lacklustre New Year celebrations, and in 2003 was the site of the triumphant homecoming of the British Rugby team from the World Cup, and a centre for demonstration against Britain's involvement in the Iraq War. The square has been associated with the many hundreds of pigeons that used to be found here, but in 2003 a bylaw was passed to make it illegal to feed them. Nelson's Column, surrounded by the four bronze lions can be found here, on the south side of the square. The north-west plinth in the square was intended to hold an equestrian statue of William IV, but remained bare since 1841 due to insufficient funds. Since 1999, it has been used to display controversial contemporary sculpture. Houses the British national collection of western European art dating from the 13th to 19th centuries. A truly awe-inspiring collection, notable works include Hans Holbein's The Ambassadors, Van Gogh's Sunflowers and Constable's The Haywain. The vast majority of art is free of charge to visit. Temporary exhibitions are generally fairly costly, but invariably well researched and presented. The audioguides are very comprehensive, have comments on most of the paintings in the museum, and are free though this fact is not advertised. A donation is suggested. In addition to courses, workshops, lectures and other events, the National Gallery has free talks and tours every day. 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 High Commission of Canada immediately opposite to Trafalgar Square maintains a regular art exhibition featuring Canadian artists.
