Art Nouveau ~ England My comment: Actually I was skeptical that this building stands in England so I tried searching for it in Google. This might be in Esch sur Alzette, Luxembourg: http://www.1902.info/city/view/id/11/l/en
Sanssouci Castle - Potsdam, Germany. Frederick the Great of Prussia built the palace as his summer escape, where he could live without a care - 'sans souci'. While Sanssouci is in the more intimate Rococo style and is far smaller than its French Baroque counterpart, it too is notable for the numerous temples and follies in the park.
