20 Fenchurch Street

The main headquarters of the Worshipful Company of Fishmongers and a Grade II* listed building.

The second biggest greenhouse in London, containing over 2,000 species of tropical plants as well as birds and fish.

The Duke and Duchess of Lauderdale's elegant 17th-century manor house, a mile or so upriver from Richmond riverside.

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.

The headquarters of world's most famous insurance market, housed in a revolutionary (at the time) bizarre, Matrix-like glass-and-steel building designed by Richard Rogers, with all support services (lifts, ventilation, etc.) suspended outside. Recognised as a masterpiece of exoskeleton architecture.

Home to the baroque composer George Frideric Handel from 1723 until his death in 1759. Some of the greatest classical music ever composed was done so at this address. The museum charts Handel's life and works and offers recitals of music in the magnificent setting of the period rooms. By contrast, next door was home to Jimi Hendrix when he lived in London in 1969, and entry to this top-floor flat is included.

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.

After visiting the two Houses, visitors pass back through St. Stephen's Hall, and through Westminster Hall. Westminster Hall is one of the few areas of Parliament in which photography is permitted, and it is a very impressive place, dating back to the 9th century. Plaques on the floor mark where the bodies of deceased members of the royal family and other distinguished individuals granted the privilege by the British government lay in state (most recently Queen Elizabeth II in 2022), and significant events which took place in the hall (such as the trial of King Charles I).

This venerable old institution was absorbed by the neighbouring Natural History Museum in 1985 but still has something of a separate identity. Unsurprisingly, devoted to all things geological with especially popular exhibits on vulcanology and earthquakes and fossils of all types. Very popular with kids and often underrated.

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

Created by Tonkin Zulaikha Greer and Janet Laurence to remember the Australians who died in both world wars. Made from Australian granite.

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.

A medieval church that was rebuilt in the late 18th century, noted for its well-preserved interior. The former churchyard was converted into a public space in 1880, called Postman's Park as it was frequented by workers from the nearby Post Office headquarters.

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.

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

An enormous, 135-metre-high observation wheel with 32 exterior glass-walled capsules. It offers incomparable views over central London and up to 40 km (25 mi) away on a good day. Tickets are sold for specific times, so if visitors wish to go on the London Eye at a specific time, they are strongly advised to book in advance, particularly in the summer. On a busy day, you can easily spend 1-3 hr queuing just to buy a ticket. However, you can also purchase tickets in advance online. Then you can collect your tickets at the London Eye in a separate queue, which takes a few minutes or less.
