The Belvedere auf dem Klausberg is a small Baroque pavilion perched on a wooded hill at the western end of Sanssouci Park, immediately north of the Neues Palais. Built in 1770 for Frederick the Great as a viewing platform over his creation, it offers a remarkable panoramic view east along the full length of the park — the only spot where the entire three-kilometre extent of Sanssouci can be seen in a single glance.
The pavilion is open for visits in summer and the exterior is accessible year-round. The climb up from the Neues Palais takes about fifteen minutes through the park's woodland. The hilltop also has a dragon-house (Drachenhaus), a chinoiserie building now operating as a café, which makes the ascent even more worthwhile. The combination of the Neues Palais, the Klausberg Belvedere, and the Dragon House covers the western end of the park in a single afternoon circuit.
