Gutenberg Castle, also known as Burg Gutenberg, is a medieval castle located in the town of Balzers in Liechtenstein. The castle was built in the early 13th century on a hill overlooking the Rhine Valley, and it has been restored and renovated over the years.

The castle originally served as a fortress, and it was expanded over time to include living quarters, a chapel, a kitchen, a brewery, and other amenities. It was occupied by various nobles and knights over the centuries, and it played a role in the political and military history of the region.

In the 19th century, the castle fell into disrepair and was used as a quarry for building materials. In the early 20th century, it was purchased by a local dentist who restored it and converted it into a museum. Today, the castle houses a museum dedicated to the history of Liechtenstein, as well as a restaurant and event space.

The castle is open to visitors, who can explore the various rooms and exhibits and enjoy the panoramic views from the castle's towers. Guided tours are available, and the castle also hosts cultural events and concerts throughout the year.
