RAF Bomber Command Memorial

This steel pedestrian bridge connecting Bankside with the City of London has all the lovely views of the Thames that you'd expect, but most of those who cross Millennium Bridge never notice its most distinctive feature. The bridge is dotted with hundreds of tiny paintings, so small that you'll probably miss them under your feet if you're not looking for them.

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

Madame Tussauds is a world-famous waxwork museum, best known for its Grand Hall, with a collection of international royalty, statesmen and world leaders. Visitors generally report that the entrance fee does not warrant the selection of waxworks on show, which rarely resemble celebrities. Also, there is usually a long queue stretching down the road.

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.

Islamic Cultural Centre and the main mosque in London. Visitors are welcome but must be suitably attired. The Mosque runs classes, prayers, talks and events.

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 unusual "walkie scorchie" profile of this skyscraper by Rafael Vinoly has seen it grab the headlines, as did the "death rays" caused by the sun's heat reflecting off the building onto the street below when it was first completed; car tyres melted and burst, and at least one man fried an egg using only the heat from the walkie talkie. Visitors can access the sky garden to see a magnificent view over the City and beyond; it's the only place you can't see the tower from! Online booking to visit during the day is essential. Alternatively, you can eat at one of the restaurants in the evening.

Museum at the former home of Dickens exhibiting writings, paintings, furniture and other items relating to the writer.

The Guildhall Art Gallery houses the City Corporation's art collection, and also runs special exhibitions throughout the year. During construction of the modern gallery, workers discovered the ruins of London's Roman amphitheatre. The gallery was redesigned, and now the Amphitheatre is open to the public within the Guildhall Art Gallery itself and also free of charge.

Discover mementoes of the famous fictional detective. In reality, this was a lodging house used in the late 1800s and has three floors. The first floor contains Sherlock Holmes' study with Watson's desk, and has bullet holes spelling the initials VR (for Victoria Regina, Latin for Queen Victoria) much to the chagrin of the landlady Mrs. Hudson. Next to that is Holmes' bedroom with a rogues' gallery containing photographs of several notable Victorian-era murderers including Lizzy Bourdain. The remaining rooms upstairs have waxwork figures and artefacts referencing the novels, as well as their adaptations to stage and screen. Photography allowed, though filming requires permission. Prebooking is recommended to circumvent long queues.

Eccentric Gothic home of 18th-century poet and author, Horace Walpole, son of England's first prime minister.

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.

An attractive Gothic Revival church, completed in 1859 to a design by William Butterfield.

This gallery houses the Tate collection of British art from 1500 through to contemporary art. A side wing collects together the gallery's collection of paintings by Turner, including some stunning seascapes. Temporary exhibitions are exceedingly varied: examples include exhibitions of Turner's paintings of Venice and the work of photographer Wolfgang Tillmans. The best known exhibition is the Turner Prize, consists of works by four artists shortlisted for the annual contemporary art prize, which runs from late October to January each year.

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.
