The world’s second largest movable flood barrier was built in 1982 at a cost of £53 million. Designed to prevent London from being deluged by storm surges moving up the Thames Estuary, the steel giant is built across a 520-metre wide stretch of the river, with ten gates dividing it into navigable spans. A triumph of engineering, it has already saved the capital from flooding some 80 times. On the south side of the river, The Thames Barrier Information Centre offers an interactive model and video about its construction. The area offers good views of the real thing in action, and features riverside walkways, a children's play area and café.
