Sorry – it’s hardly original. The eagle-eyed will have spotted one or two not-very-cryptic photo captions relating to Ironbridge power station, which operated for the last time just over four years ago. Since then, it has been decommissioned, and now is undergoing demolition. So far, such work has not been obvious, but this morning, at 11am, the towers came down. They were so big that they always seemed to be nearer than they were – the closest was about 2/3 of a mile away from our vantage point, the furthest not far short of a mile. Just before 11, we heard warning sirens – and then the towers began to fall. The boom of the explosive charges, like the crack of thunder following a nearby bolt of lightning, came when the towers were well on their way down. Yes, we know why, but the laws of physics can easily be forgotten in a moment of excitement.

Now they’re history. The intentionally salmon-pink towers were quite an icon in this part of the world, and it was a sad sight to see them being reduced to rubble (and an awful lot of dust!). However, the Severn Gorge already looks more rural, like it did in the early 60s, and when the chimney and turbine halls have gone, the riverside here will look completely different, in closer accord with a greener future.
