30 St Mary Axe (The Gherkin)

This guide to 30 St Mary Axe in London begins on the night of April tenth, nineteen ninety-two, when a bomb parked on this street killed three people, including fifteen-year-old Danielle Carter, and tore through the Victorian Baltic Exchange that had stood here for generations. You'll hear about the fight over whether to save the ruined exchange, and how Swiss Re and architect Norman Foster ended up building on the rubble instead. Walk a slow loop around the base of the tower and take in how the glass panels catch the light differently as you go.
