The Millennium Tower is the second tallest building and fourth tallest structure in Austria at 171 metres. The tower is located in the Brigittenau 20th district in Vienna. An antenna mounted on top of the tower brings the architectural height to 202 metres but does not count to its overall height.

The tower has 51 floors, serves both commercial and residential purposes, and is the focal point of a complex known as "Millennium City". It was completed in 1999 for the coming of the third millennium. The office tower has a gross floor area of 47,200 m2 (508,000 sq ft), of which 38,500 m2 (414,000 sq ft)is used as office space.

The Millennium Tower was built in an extremely short construction time: Thanks to efficient organization of all work steps and modern building techniques have created an average of 2 ½ floors a week and the building completed in 1999.
The shape of the tower is formed by two clasped each other fully glazed cylinder which is supported by a steel composite structure. The operating contractor was the consortium Habau - Voestalpine - MCE. In the building there are around 120 companies office space, including major international companies such as Xerox. Owner George Stumpf sold the Millennium Tower in Vienna on July 25, 2003 along with the associated Millennium City to the Hamburg-based issuing house MPC (Münchmeyer Capital). The purchase price was 360 million euros, which is close to 15-times the annual income of 24.5 million euro (2002) corresponds to the Millennium City, which is next to the offices in the Tower and form a shopping center, residential buildings and the largest cinema complex in Austria. Taking into account the building costs of 145 million Euros, there is a profit of 215 million euros.
