"Sanssouci is the former summer palace of Frederick the Great, King of Prussia, in Potsdam, near Berlin. It is often counted among the German rivals of Versailles. 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. The palace was designed/built by Georg Wenzeslaus von Knobelsdorff between 1745 and 1747 to fulfill King Frederick's need for a private residence where he could relax away from the pomp and ceremony of the Berlin court. The palace's name emphasises this; it is a French phrase (sans souci), which translates as "without concerns", meaning "without worries" or "carefree", symbolising that the palace was a place for relaxation rather than a seat of power. The name in past times reflected a play on words, with the insertion of a comma visible between the words Sans and Souci, viz. Sans, Souci.[1] Kittsteiner theorizes that this could be a philosophical play on words, meaning "without, beware" or it could be some secret religious message which nobody has interpreted, left to posterity by Frederick II.
Sanssouci is little more than a large, single-story villa—more like the Château de Marly than Versailles. Containing just ten principal rooms, it was built on the brow of a terraced hill at the centre of the park. The influence of King Frederick's personal taste in the design and decoration of the palace was so great that its style is characterised as "Frederician Rococo", and his feelings for the palace were so strong that he conceived it as "a place that would die with him".[2] Because of a disagreement about the site of the palace in the park, Knobelsdorff was fired in 1746. Jan Bouman, a Dutch architect, finished the project ° .(from wikipedia)
