Regent's Park

Probably the most popular of all the museums here and a must see for many visitors to London. Home to at least 70 million specimens from across all the life sciences. It's difficult to say what the most popular exhibit here is; the blue whale which towers over the entrance hall, the (now slightly tacky-looking) animatronic Tyrannosaurus rex in the dinosaur gallery, or the life-size model blue whale in the mammals gallery. Also well worth a check are the Darwin Centre (book on a free tour to see some of the most interesting, and sometimes gruesome, specimens not on public display); and the studio dedicated to BBC wildlife personality extraordinaire, David Attenborough. The NHM's "Earth Galleries" were once the adjacent Geological Museum, an independent institution until the 1980s, and still located in a separate building with a separate entrance.

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.

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.

Includes a small but beautiful quad and an interesting Neo-Classical facade. The core buildings of UCL were built after the university's foundation in 1826.

This church on the bank of the Thames was built in 1157. It is the only church in London with chained books. A statue of Thomas More sits in front of the church.

Designed and built in 1619-1622 by the Neo-Classical architect Inigo Jones, The Banqueting House is now all that remains of Whitehall Palace, the sovereign's principal residence from 1530-1698 when most of it was destroyed by fire. Renowned for its architecture and paintings (by Rubens, among others), the building is also famous for being the scene of Charles I's execution in 1649 at the end of the English Civil War.

A branch of the Imperial War Museum, the Cabinet War Rooms preserves the underground corridors and rooms from which Churchill and the cabinet directed the war against Hitler and the Nazis, maintained almost exactly as they were left in 1945. In 1984, IWM opened the rooms to the public for the first time. In 2005, the attached Churchill Museum was opened as the world's first permanent museum dedicated to the life and wartime achievements of Sir Winston Churchill. Audio guides are included in your admission. No cloakroom, no rucksacks, no suitcases. Café is open daily from 10am to 5pm. Hot food is served until 3pm.

A retirement home for soldiers created by King Charles II. Tours around the listed building and grounds are regular and include the museum (which can be visited separately) whose exhibits contain military memorabilia donated by Chelsea Pensioners over the years.

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.

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.

The oldest of the Royal Parks of London.
