The Hohensalzburg Fortress, which literally means 'high fortress of Salzburg', is a medieval fortress located at the top of the Festungsberg hill. It has a length of 250 meters and a width of 150 meters, which makes it one of the largest preserved medieval castles in Europe. There is one permanent exhibition in the fortress dedicated to the history of this building and city.
Inside the fortress you can see rooms formerly inhabited by archbishops, as well as representative rooms and a chapel. The castle's major curiosities include the organ known as the Salzburg Bull. They were constructed in 1502 and then restored in the 18th century. They have 200 pipes.
Construction of the castle was started in the 11th century. The current shape was given by significant fortifications from the 15th, 16th and 17th centuries. At the end of the 19th century, the fortress was a tourist attraction. In the first half of the 20th century, the fortress served as a prison for a short time. Currently, a museum operates here, and concerts and other cultural events are organized in the large concert hall.
