I figured that would be under the petroleum and electricity column but sure, that's definitely true. They also use some mighty damned big trucks and explosives in quarries. I wonder how much of the 80 years of building a cathedral is just sourcing and paying for the stone.

I also love the solution Christopher Wren came up with after the Great Fire. Everyone wanted him to design their church. He made a compromise: I'll build you your church but you don't get a bell tower until after everyone else gets a church. So he went around building churches and then swung back through to add bell towers onto them.
