History of Hause des Meeres

On November 26, 1957, the Association for Marine Biology was founded, which at that time already set itself the goal of creating the “Haus des Meeres” in the former Esterházypark flak tower.

At that time, Haus des Meeres was the first seawater exhibition in Austria and only occupied 1 ½ floors of the flak tower, which was mostly empty at the time.

This was completed in July 1944 and functioned as a fire control tower until the end of the war. On the roof of the tower was the so-called "Würzburg giant". This was a radar device that was protected from air raids in the shaft by 3.5 meter thick reinforced concrete walls.

The fact that the zoo is housed in a former flak tower is a special feature and is the subject of the permanent exhibition, Remembering Inside".

The exhibition is located in the former command center and sheds light on the dark past of the flak tower. The exhibits include original exhibits and wall panels about the history of the building, which can be viewed in the staircase, and most of which have been preserved in its original condition. The permanent exhibition is accessible as part of a guided tour. You can find out more about this here.

Today, Haus des Meeres covers an area of 8,000 m², spread over 11 floors, and has been visited by more than 11.7 million guests since it opened in 1957.
