It was one of the jewels in the crown of Georgian London: a building so unusual that a suspicious public were unconvinced it would remain standing when it was built in 1762.  Designed at the height of the 18th century craze for Chinoiserie, The Great Pagoda at Kew was famously adorned with 80 brightly coloured wooden dragons. The eye-catching dragons were the talk of the town for 20 years, before disappearing in the 1780s, rumoured to be payment for the Prince Regent’s gambling debts.

Charles de Gaulle, a junior minister in a collapsing government and a relatively junior general in an army that was ceasing to exist, landed at Heston airport after a gruelling and perilous flight from Bordeaux, on Monday 17 June 1940. Few of his British hosts knew who he was, Winston Churchill being the exception. During his visits to France, Churchill had immediately noticed “a young, energetic general called de Gaulle.” `(In Gabriel Le Bomin’s biopic of de Gaulle, which features the early days of the two men’s relationship, Churchill is brilliantly played by Tim Hudson – who is also a London Blue Badge Guide!)
