Can't have an Arch thread without FLW. A lot of his work is local to me, and I've visited a few places, but that was a long time ago when I was in school. You can see his influence in a lot of the later buildings around here too, so Frank Lloyd Wright 'inspired' designs are pretty common. I just perused a few images, here's some of the more popular works he's done:
Falling Water
Robie House
The Rookery
Unity Temple
Larkin Building
Taliesin West (his winter home)
