The hunting lodge of Electoral Prince Joachim II was designed and built by royal architect Caspar Theiss in 1540. Hidden away in the dense Grunewald forest, the prince adored hunting and had other lodges built in Köpenick and Potsdam during the same period. In the early 18th century, Friedrich I added baroque elements to the building, but the impressive main hall with its intricately painted ceiling has remained unchanged over the centuries. The Jagdschloss Grunewald now houses a museum boasting an impressive collection of works by German and Dutch painters of the 14th-19th century like Rubens, Lievens and Cranach. Countless hunting trophies can also be seen here.
