The Millennium Tower is the second tallest building and fourth tallest structure in Austria at 171 metres. The tower is located at Handelskai 94-96 in the Brigittenau 20th district in Vienna, Austria. An antenna mounted on top of the tower brings the architectural height to 202 metres but does not count to its overall height. Millennium Tower was designed by the architects Gustav Peichl, Boris Podrecca and Rudolf Weber.
