The famous Thames Barrier defends London against the flooding that has become an even more pressing concern for the UK over recent years. This amazing feat of engineering was raised more than 50 times during the storms of 2013/2014 to protect the capital and its 1.25 million residents.
Each of the barrier's 10 gates reaches 520m across the Thames and is made of pure steel. They work by lying flat on the river bed when the barrier is open and then rotating upwards until they block the river when closing. Excess river flow then fills the reservoir that the barrier creates when it's closed just after low tide.
