St. Margaret's Church

Substantial nature reserve on the old disused Barn Elms Reservoirs. A major wetland habitat for wintering wildfowl and an excellent choice for any keen birders visiting London, and an entertaining place for kids to learn about nature

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.

The ruins of a church dating back to Saxon times, rebuilt by St Dunstan in 950, destroyed in the Great Fire of London, and then rebuilt by Sir Christopher Wren in 1697. Most of the church was destroyed during the blitz, leaving only the tower (dating from Wren's time) and hollowed-out walls (from an 1817 reconstruction). The ruins are now overgrown with picturesque vines and trees, and were converted into a public garden in 1967, complete with benches.

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.

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.

A neoclassical church that stands opposite the National Gallery. Since World War I, the homeless have sought shelter at this church, a tradition that continues to this day.

Site of the London residences for the Prime Minister (No. 10) and the Chancellor (No. 11).

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.

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.

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

Properly St Lawrence Jewry next Guildhall, it is the official church of the Lord Mayor 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 most senior of the Royal palaces in London (built between 1531 and 1536) and the official seat of the monarch.
