From 2009 the palace is the main building of the City Museum of Wrocław and presents, among others the exhibition “1000 years of Wrocław”.
The Royal Palace (Pałac Królewski) was called Spaetgen’s Palace, from the name of one of the first owners. In 1717 baron Heinrich G. Spaetgen bought a small baroque mansion close to Rynek. After his death in 1750, a Prussian King Frederick II bought the palace. It became a royal mansion, and Wrocław joined Berlin and Königsberg (today’s Kaliningrad) as a residence city.
The next Prussian kings extended the palace, changed its design and character. In the middle of the 19th century the palace extended itself from Wolności Square to Kazimierza Wielkiego Street. After the fall of the empire the palace was taken by the city authorities, in the 20s the Palace Museum was opened. During World War II the building was seriously damaged.
