Art Nouveau Buildings

Brussels has dozens of Art Nouveau buildings, from the early 20th century.  This is simply a typical group.  
Next morning after a latish night: The days outing was mainly to a marvelous exhibition on Christo (1982- ). His main thing was wrapping buildings, but much more.  The show consists mainly of his artistic depictions of his works, including maquettes--difficult to describe here, but utterly fascinating. Christo worked with his wife, Jeanne-Claude (1935-2009) and their entire career, from the early 1960s to nearly the present. We saw only one of his works: The Gates, in Central Park, NYC--unfortunately on only one day, before we had to leave on a long-scheduled trip.  I've put up an extra, with a huge model of his wrapped Pont Neuf  (1985) in Paris.
