Demolished in 1962, there was a shot tower on the South Bank next to the Festival Hall.
Sir Hugh Casson, who had been the Director of Architecture for the Festival of Britain in 1951, described the tower as "an extraordinary device. It's a factory chimney, with a staircase inside it, and you take hot lead up to the top, and you drop it down, in drops, and the drops don't make tears as you'd expect, to get thicker as they go, they're absolutely perfect globes, and they're tiny, you see, as you know, I mean, they're absolutely wee, like the shot you get inside a cartridge. And there were two old men, one at the bottom and one at the top. The one at the top was the one with the hot lead, and he dropped it down into a cold bucket at the bottom, and it cooled it off at once, and then it was taken away and sold. And these two old boys were rather like two old fishermen in a boat, they'd been there for years. And they didn't speak, most of the time they were separated by 150 feet of shaft."
Who knew?
, lots of talk of banning it, but for the moment it survives
