Vaduz Castle.

“It is the palace and official residence of the Prince of Liechtenstein. The Princely Family of Liechtenstein acquired Vaduz Castle in 1712 when it purchased the countship of Vaduz. (Construction started in the 12th century.)

“The castle underwent a major restoration between 1905 and 1920, then again in the early 1920s during the reign of Prince Johann II, and was expanded during the early 1930s by Prince Franz Joseph II. Since 1938, the castle has been the primary residence of Liechtenstein’s Princely Family. The castle is not open to the public as the princely family still lives in the castle.”
