The Thames Barrier is one of the largest moveable flood barriers in the world. It protects over 125 square kilometres of London and over 375,000 properties, historic buildings including the Houses of Parliament, offices, power supplies, tube lines and hospitals to name a few.
The Environment Agency maintains and operates the Barrier as well as the capital’s other flood defences. The Barrier is also one of London’s most striking and famous landmarks. With its distinctive stainless steel piers it spans 520 metres across the Thames near Woolwich.
Visit the Thames Barrier Information Centre, based next to the Thames Barrier in Woolwich, to view this amazing structure.
