Which palace in Potsdam, Germany, was built by Frederick the Great and is a UNESCO site?

The palace in Potsdam built by Frederick the Great and protected as a UNESCO site is Sanssouci Palace. Designed as the Prussian king’s private summer retreat, it is a compact Rococo residence surrounded by gardens, terraces, and park buildings.

Architect Georg Wenzeslaus von Knobelsdorff designed Sanssouci between 1745 and 1747. Frederick wanted an informal residence where he could escape court ceremony, pursue music and philosophy, and enjoy the landscape. The name Sanssouci comes from the French phrase meaning “without worries” or “carefree.”

Unlike the imposing New Palace, which Frederick later built to display Prussian power, Sanssouci is a low, intimate building with only about ten principal rooms. Its south façade overlooks terraced vineyards created on the hillside, while the surrounding park contains the Picture Gallery, New Chambers, Roman Baths, and other historic structures.

Sanssouci and the surrounding palaces and gardens of Potsdam became a UNESCO World Heritage site in 1990. Its relaxed scale and vineyard setting distinguish it from Charlottenburg Palace and from the much larger Versailles.
