The Fliederbrunn Imperial Palace (Hulstrian: Schloss Fliederbrunn) in Kien, Greater Hulstria, is one of the most important cultural monuments in the Imperial Crownlands and since the 1900s has also been one of the major tourist attractions in Kien. The palace and its gardens illustrate the tastes, interests and aspirations of successive Rothingren monarchs. Within those gardens is the Fliederbrunn Tiergarten, the world oldest continuous zoo. Fliederbrunn serves as the winter residence of the Imperial Family, however Phönixstein Castle is the family's prefered Summer Residence, and Fliederbrunn is therefore officially known as the Winter Palace; Fliederbrunn Palce, due to its influence, in the media is a commonly used term to refer and symbolize to the monarch as a whole.
