The Baroque Poppelsdorf Palace was begun in 1715, right where Poppelsdorf Castle stood until it was flattened during the Cologne War in the 1580s.

The palace is a Baroque treasure intended as a pleasure palace for Joseph Clemens, the Archbishop Elector of Cologne.

For almost 200 years the building and its grounds have been owned by the University of Bonn.

The facade has a French classical design, with quoins, a double stairway and mansard roof.

Make sure to go through to the delightful arcaded central courtyard, which is in an Italianate style on a circular plan.
