Vaduz Castle, Liechtenstein
Squeezed into lovely alpine terrain between Switzerland and Austria is the tiny country of Liechtenstein. Technically a Principality, Liechtenstein is only about 25 km long by 13 km wide. But it holds a lengthy history. Its 16th century castle, Vaduz Castle, is a landmark of the Principality and residence of the Princely family. For this reason it is not open to the public. But follow the walking path behind Vaduz and you’ll be led up to see the exterior from a close vantage point. As a bonus, the short trail offers a stunning view of Vaduz and the Rhine Valley.
