S3·E5 London: Mod and Trad

London is quintessentially English, yet cosmopolitan. We check out the new — the Millennium Bridge and the British Museum's Great Court, and admire the old — well-wrapped mummies and a rare Leonardo. After bantering with Beefeaters at the Tower of London, we do some riverside beach-combing. Strolling the trendy South Bank of the Thames takes us from the Tate Modern to the dizzying London Eye.
