About Haus des Meeres

Haus des Meeres (HdM), translated as 'House of the Sea,' is a prominent public aquarium and zoo situated in Vienna, Austria. Its unique location within a former World War II concrete flak tower in Esterhazy Park, Mariahilf district, makes it a distinctive landmark. The institution is managed by Aqua Terra Zoo, a private non-profit organization, and serves as a significant attraction, drawing hundreds of thousands of visitors each year.

Background and Construction

The building that now houses Haus des Meeres was originally constructed as a fire control flak tower between October 1943 and July 1944. Standing 47 meters (154 ft) tall, this imposing concrete structure was part of a larger defensive network in Vienna during the war. After the war, the tower had a varied history, serving temporarily as a hotel and then as a fire station before its transformation into an aquarium.

Transformation into an Aquarium

The transformation of the flak tower into the Haus des Meeres began in November 1957 when volunteers moved into the structure. Initially, only a small portion of the tower was habitable for exhibitions due to its use by firefighters. Over time, the aquarium gradually expanded its presence, occupying more of the tower's floors as they became available. This expansion included the addition of glass wings in 2000 and 2007 to house reptiles and tropical birds, and extensive renovations enabled the opening of new floors. The tenth floor is dedicated to World War Two exhibits, recreating a flak tower control vault.

Notable Features and Visitors

Haus des Meeres is home to over ten thousand aquatic beings and covers an area of approximately 4,000 square meters (43,000 sq ft). A significant exhibit is its large shark tank, capable of holding 300,000 liters (79,000 US gallons), which houses blacktip reef sharks. The aquarium has seen substantial visitor numbers, reaching a record high of 650,000 in 2012. Despite the financial challenges of maintaining the historic structure, the aquarium has consistently attracted more visitors, solidifying its position as a popular tourist attraction in Vienna.
