The Dragon House (Drachenhaus) on the Klausberg hill at the western end of Sanssouci Park is a chinoiserie folly built in 1770 — a small building shaped like a Chinese pagoda with a dragon weathervane on top, designed by Carl von Gontard for Frederick the Great. It originally housed the vineyard keeper for the park's western vineyards. Today it operates as a small cafe, making it the best possible reward for climbing the Klausberg hill to the Belvedere.
The building is immediately recognizable from below: a multi-tiered Chinese pagoda shape, painted in warm colours with carved decorative details. It sits in a clearing among the park's western woodland, about fifteen minutes' walk from the Neues Palais. Visiting the Dragon House, the Klausberg Belvedere directly above it, and the Neues Palais at the base of the hill combines three distinct experiences in a single two-hour circuit of the park's western section.
