Quote - The Moscow Kremlin in Russia from around the 1400's.
I guess ya would consider the ruffs parametric and generative based.
Rumor has it the royalty at the time killed the Architect that designed the Kremlin.
So there wouldn't be another building like it.
Guess the royalty never herd of parametric and generative.

You mean the "domes" of St Basil's Cathedral, on Red Square, towards the Saviour's Gate into the Kremlin?

Been there, back in the early nineties... it's an awesome building.
