1. Westminster Bridge is green and Lambeth Bridge is red. But do you know why? It is because the former is next to the House of Commons and the latter is next to the House of Lords. Everything in the House of Commons is coloured green because green used to be the cheapest dye you could get. Everything in the House of Lords is red because red used to be the most expensive dye you could get.
2. In the 1960s, Number 10 Downing Street was completely rebuilt because it was falling apart.

10. The Oldest English Heritage Blue Plaque can be found in St James's King Street. It is dedicated to Napoleon III, and put up in 1875. He moved to England in 1971 after fleeing France in exile, and died in 1873 after having his gallstones removed.
