Clapham Common

A lovely park on the southern banks of the Thames known or its wildlife and some splendid examples of mature trees.

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

This enormous arch was built in front of Buckingham Palace. In 1851 the expansion of the palace meant the arch could no longer remain where it was, so it was moved to this point on Hyde Park. It now stands rather sadly on a large traffic island, but the subway beneath the roads means you can stop off at the Marble Arch on your way from Oxford St to Hyde Park.

Medieval Grade I listed church. This church played a key role in the English Revolution and was the parish church of some of the most decisive Puritans: Oliver Cromwell was married and this is where John Milton was buried. It was the home of the Morning Exercises. The tower remains from the original building; the rest was destroyed in the Blitz but rebuilt based on the original plans.

Properly St Lawrence Jewry next Guildhall, it is the official church of the Lord Mayor of London.

This garden square was established by Lord Southampton in 1665 and is the oldest square in London. It was opened to the public in the 1950s. The square is surrounded by a number of beautiful 18th- and 19th-century buildings and terraces.

The world's main marketplace for ship broking.

A splendid Regency house with enormous gardens and woodlands. The gardens alone are worth the visit and are a superb example of 18th-century landscaping. On show at the house is art by masters such as Rembrandt, Turner, Reynolds and Vermeer, and the gardens have a very notable sculpture by Henry Moore. A regular program of outdoor opera takes place here every summer. Movie buffs will recognise Kenwood from Mansfield Park among other famous films. Administered by English Heritage, separately from the rest of Hampstead Heath.

Worth a quick visit if you are passing. The brick and stone neo-Byzantine Catholic Cathedral (not to be confused with the much more famous Westminster Abbey) is near Victoria Station, just off Victoria Street. Construction started in 1895, and some of the interior is still unfinished. The Treasures of Westminster Cathedral exhibition is inexpensive and worthwhile for learning the history of the cathedral, there are interesting exhibits including a 1:28 wooden scale model uses by the architects. Has a café and gift shop.

The oldest of the Royal Parks of London.

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 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.

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.
