Palais Schwartzenberg Plaque, Wien (Vienna), Austria, 2013

This is the historical marker for the Schwartzenberg Palace, built by the Schwartenberg family (if I'm not mistaken) between 1697-1704. The Schwartzenbergs are Austrian, but the Czech MP, Karel Schwartzenberg, is one of them. This isn't so surprising given the historical connection of the Hapsburg Monarchy, which ruled Bohemia, to a greater or lesser degree, from 1526 to 1918.
