Belvedere Castle, also known as Schloss Belvedere auf dem Pfingstberg in German, is a beautiful neoclassical palace located in Potsdam, Germany. It was built in the early 19th century for Prince Wilhelm of Prussia, who was later to become Wilhelm I, the first emperor of a united Germany.

Belvedere Castle was designed by Karl Friedrich Schinkel, a famous architect and painter of the time, and was constructed between 1847 and 1863. The castle is situated on a hill called Pfingstberg, which offers stunning views of Potsdam and the surrounding countryside. The name Belvedere means "beautiful view" in Italian, which is a fitting name for this magnificent palace.

The castle consists of two main parts: the lower castle, which serves as a gateway to the upper castle, and the upper castle, which is the main palace building. The upper castle features a grand ballroom, a library, several drawing rooms, and numerous bedrooms. The interior of the castle is decorated with beautiful frescoes, intricate plasterwork, and ornate furniture.
