The Belvedere auf dem Klausberg is an observation tower located in Sanssouci Park near Potsdam, Germany. Constructed between 1770 and 1772 for Frederick II of Prussia, it was designed by architect Georg Christian Unger in a classical style inspired by a sketch of an ancient Roman temple by Italian archaeologist Francesco Bianchini. The structure features two floors with a rooftop terrace, surrounded by twenty columns—ionic on the lower level and corinthian on the upper. Each floor has eight arched windows offering panoramic views, and two belvedere terraces face east and west. The cupola is adorned with twenty sculptures depicting ancient mythological figures. Originally, the lower floor was decorated with white and gray Silesian marble and red jasper, while the upper floor has been restored to its original appearance with green-blue marmorized stucco walls, gilded window ornaments, and parquet flooring. Severely damaged during World War II, the Belvedere was restored between 1990 and 2002 and is now managed by the Foundation for Prussian Palaces and Gardens Berlin-Brandenburg. It is part of the UNESCO World Heritage site "Palaces and Parks of Potsdam and Berlin" and hosts cultural events like the Music Festival in Potsdam.
