The Belvedere on the Pfingstberg (German: Belvedere auf dem Pfingstberg) is a palace in the northern part of the New Garden in Potsdam, Germany, atop Pfingstberg mountain. It was commissioned by Friedrich Wilhelm IV and is only one part of an originally substantially more extensive building project. The twin-towered building was modeled on of Italian Renaissance architecture, and it was built between 1847 and 1863 with an interruption from 1852 to 1860. From sketches of from the king, the architects Ludwig Persius, Friedrich August Stüler and Ludwig Ferdinand Hessian drew up details plans.
