Thames Barrier

The Thames Barrier looks best when it’s raised, and the only guaranteed time this happens is when the mechanisms are checked once a month. For exact dates and times, check the website of the Thames Barrier Information Centre. Each of the 10 steel gates is 20m high and weighs 3300 tonnes.
