Storeton Quarry stone was used in the building of the Empire State building in America
Ive heard that said before, but I could never find proof it was true any where. I know its off topic, but have you got any links?(besides Wikipedia)
I think the story may be apocryphal. The Empire State Building was built in 1929, by which time the main quarries had been abandoned, and were soon to be filled with the waste from the Queensway tunnel. The South quarry, on the river side of Mount Rd. was still in intermittent operation, but the Storeton tramway had been dismantled so any movement of stone would have been by road.
The best clue I have is the book "The Storeton Tramway", by R,C,Jermy. In it, he says that Storeton Stone was used for: Birkenhead docks, Hamilton Square, Sankey Viaduct, the original Liverpool Philharmonic Hall, a house in Ireland and one in Essex. If it had been used in the Empire State Building I think Mr.Jermy would have known and mentioned it.
