Thames Barrier

The Thames Barrier has continued to quietly perform its job of protecting Londoners and its millions of viewers ever since its construction in 1984. Its simple purpose is to prevent London from flooding due to storms that make their way through the Thames Estuary. Stretching 520 metres across the Thames, the huge steel structure is made up of ten separate gates which operate to set levels depending on weather conditions.

It’s a little known fact that the barriers have saved London from being flooded on countless occasions, and this triumph of design and engineering has more than earned its £53 million construction costs back.
