With its bustling streets, green parks and rich history around every corner, London always has plenty to catch your eye. What is not so well known is the science that keeps the city alive. As you discover the engineering of Tower Bridge, the geology of our streets and the biodiversity of the River Thames, the Royal Society's guided walking tours explain how science has contributed to the city you see today and delivers you straight into the heart of the festival.
