This Greek temple-style building is the French National Assembly Building, also known as the Palace of Bourbon, built in 1722 for the Duchess of Bourbon, daughter of King Louis XIV. The French flag and, of course, the European Union flag were flying at the door. Portrait sculpture at the door. I vaguely remember the LP Encounter Paris I took that day, which introduced these portraits, but LP is not at hand, I can't remember it...
