Stump the German

[Eva Elisabeth]

Brilliant, Laurie, I took the pic in Spain (and as for the idea of African slaves instead of Indians I think it was Bartolomé de las Casas).
OK, back to the exact location and designer who actually was an architect.
Hint #1: The place as well as six other places/buildings he designed are UNESCO World Heritage.
Hint #2: The city is comparable to Richmond as a capital...
