Originally known as the Camesina House (named after the family that owned it since 1720) the structure was constructed as a two story house in the 17th century. Mozart and his family lived here between 1784 and 1787. Now a museum, this is the only surviving known residence of Vienna's great composer. The apartment consisted of four large rooms, two smaller rooms, and a kitchen. On the 150th anniversary of Mozart's death (1941) Vienna opened his former rooms to the public as part of the "Imperial German Mozart Week". Today as a museum, it presents information about the composer's life, along with historical exhibits. Again, as in many museums throughout Europe, interior photographs were not allowed.
