Tower Bridge, one of the most famous bridges in the world, is 125 years old this year. The iconic structure is one of London’s most visited attractions and a defining feature of our capital. David Laird, an expert on the bridge, will share with us the stories behind the engineering, the people, the architecture and the city that created this landmark.

Want to visit? Tickets to the bridge cost £9.80, but Tower Hamlets residents with proof of address and photo ID get in for only £1, and accompanying children are free.
