The Haus des Meeres (HdM, English: House of the Sea) is a public aquarium in Vienna, Austria. It is located in Esterhazy Park in the centre of Mariahilf district, one block south of the busy Mariahilfer Straße. The Haus des Meeres houses over ten thousand aquatic beings on an area of around inside a tall concrete flak tower built during World War II. In 2012 the Haus des Meeres attracted a record high of 650,000 visitors. The Haus des Meeres is managed by Aqua Terra Zoo, a private non-profit organization which, according to its web site, receives only marginal financial support from municipal authorities. However, the maintenance costs for the former flak tower are paid by the taxpayer.
