Where is the largest collection of Bauhaus style buildings in the world?

Combining Art Deco along with elements suitable to the climate and location: brilliant! Nothing is so soothing to the eye than rounded corners and walls. Lovely.

I would love to go there but there is so much unrest across the ocean. I live in the state if Kansas in the USA. Nice and quiet!! My town doesnt even have a traffic light!! No locked doors either!!
