The Vaduz Castle, located in Liechtenstein, was given this title due to its location’s capital – Vaduz. It’s the symbol of the country, a most majestic sight that I have personally experienced and this is also the home of the Princely Family of Liechtenstein. Unfortunately, this site is not open to the public, but it is still worth admiring from the outside and enjoying the views of the Alps. It’s interesting to note that the roads actually lead directly to the castle and are in a curved, steep and narrow manner.
