The Thames barrier spans 520 metres across the Thames at Woolwich Reach with the 10 steel gates raised monthly for testing.
There is an exhibition with a 10 minute video and a working scale model. Also riverside walkways, children’s play area and Thames Barrier Cafe.
The £500 million Thames Barrier was inaugurated by HM The Queen in 1984. The Environment Agency maintains and operates the Barrier as well as the capital’s other flood defences. These defences include floodgates like the Barking Barrier, and raised river banks.
The idea for a barrier started as early as 1953, after a great flood that drowned over 300 people. Tides rushing in from the sea used to be the main cause of flooding in London.
Work on the barrier started in 1974 and took ten years to complete. To discover more please follow the link.
