It is crazy that the Palace of Versailles was built when the country was in economic disaster.  King Louis 14th gives kings a bad name and was a total ego maniac.  He almost kind of created his own little city within France.  It is jaw dropping beautiful and even if someone argued against its preservation, it's so huge it's impossible.  Historically and artistically there is no way this couldn't be preserved, it's too big to ignore and too beautiful to overlook.  Having said, I agree, it should and most definitely will be preserved.  I love the Taj Mahal too!  Do you like The Palace of Versailles or the Taj Mahal better?
