- Blue!
The Creation of the World, stained glass window. By Chagall, of course. Not many artists get to co-create their own galleries. - The ostriches!
The coat of arms of Leoben is an ostrich. Apparently, they were considered as the only animals being able to eat iron. And since this is a mining town... ostriches are the obvious choice. - Fonte Gaia
The first fountain was built in 1342, this one was made in 1419 by Jacopo della Quercia.
