An iconic landmark across the Thames Estuary from Southend has been demolished.
The chimney at the former Isle of Grain power station in Kent came down at 11am.
It took thirty seconds for the blast to travel across the estuary and be heard by the hundreds of people watching along the shoreline.
It was just over 800 feet tall, slightly shorter than the Shard but taller than Canada Tower at Canary Wharf.
Some smashing facts:
* Grain A Power Station’s chimney is 244m (801ft)
* It is the tallest concrete structure ever to be demolished in the UK
* It was taller than 55 double decker buses stacked on top of each other
* It was two and a half times the height of Big Ben.
* Around 40,000 tonnes of concrete were brought to the ground during demolition
Site owner Uniper urged people to watch the detonation at a safe distance and in a location that didn’t cause any disruption to local traffic.
Grain A was officially opened in 1979 and, with a capacity of up to 1320MW, it was able to produce enough electricity to power over one million homes. The plant closed in December 2012.
