What to do in London

There's a version of London for whichever mood strikes you, and most visitors end up doing all of them in a single week. Watch the scarlet-coated guardsmen at Buckingham Palace, then queue politely for the crown jewels at the Tower of London; do it in a chauffeured black cab if walking feels like hard work. History buffs will want Westminster Abbey and a climb to St Paul's Whispering Gallery, while the more energetic among you can explore the Square Mile before hunting street art through Shoreditch. Greenwich rewards a slower afternoon: the Cutty Sark, the Royal Observatory's meridian line (one foot in each hemisphere, camera ready), and a cruise back up the Thames with a glass of something cold. Follow 007 through Mayfair, the Beatles across Abbey Road, or simply settle into Borough Market and a proper afternoon tea. London never really switches off.
