Potsdam’s Sanssouci is a relaxing royal treat only 30 minutes away by train from bustling Berlin. In French, the palace’s name means “without a care;” it was a quiet refuge for the Prussian king. His final wish was to be buried there, a desire not granted until after German reunification. This UNESCO World Heritage Site, built between 1745 and 1747, is known for its treasures inside and out. Highlights include the white and gold Marble Hall reception area, loosely based on the Pantheon in Rome, the many paintings by one of Friedrich’s favorite artists, Antoine Watteau, and the Voltaire Room, with its carvings of birds, flowers and fruits, named after the French philosopher and frequent palace guest. The large landscaped park is dotted with fountains, with faux ruins and classical statues among the many points of interest.
