In Vienna‘s first quarter, on the corner between Universitätsstraße and Reichsratsstraße, very close to the Votiv Church, there is a building with these sculptures:
The first one looks kind of Greek, though I don’t find anyone with whom to identify him with any certainty.
The spot seems pretty well known. I see tourists taking pictures every day, but so far none has been able to tell me, who they are.
Judging from questions about Koxinga, etc. this should be on topic.
