Vaduz Castle is a medieval fortress located in the town of Vaduz, the capital of Liechtenstein. The castle dates back to the 12th century and has been the official residence of the Prince of Liechtenstein since 1712. The castle is situated on a hill overlooking the town and the Rhine River valley, providing stunning views of the surrounding area.

The castle was first mentioned in historical records in 1322, but it is believed to have been built earlier than that, possibly in the 12th century. Over the centuries, the castle has undergone several renovations and additions, including the addition of a chapel in the 16th century and a residential wing in the 17th century.

Today, the castle is closed to the public as it serves as the private residence of the ruling Prince of Liechtenstein and his family. However, visitors can view the castle from outside and take in the picturesque views of the surrounding landscape. The castle is also illuminated at night, making for a beautiful sight.

In addition to its role as a royal residence, Vaduz Castle has also played an important role in Liechtenstein's history. During the 18th and 19th centuries, the castle served as a military barracks and was used as a shelter during times of war. Today, the castle stands as a symbol of the country's heritage and identity.
