Phönixstein Castle (Hulstrian: Schloss Phönixstein), often inaccurately called in English "Phoenixstein Castle", is the primary Summer Residence of the Hulstrian Imperial Family, the Rothingren-Traugotts. The Castle is located just outside of Hulstrian capital city of Kien in a small village named Phönixsteindorf after the Castle. The Castle is reguarded as the private property of the Rothingrens, and is therefore not open to the public.
