Nomenclature
"Wien" is the German word for "Vienna"; but the "Wien" in the name of the theatre is not the name of the city but rather the name of the Wien River (Wienfluss), which once flowed by the theatre site; "an der Wien" means next to (that is, on the banks of) the Wien. In modern times the name has become somewhat opaque, since the river has been covered over in this location; the covered riverbed now houses the Naschmarkt, an open-air market.
