This mostly residential tower is the tallest building in Mulhouse and indeed, in all of Alsace. Its triangular shape symbolizes the three countries that come together in this region: France, Germany, and Switzerland. Including basements and mezzanines, there are 37 levels; the rotating restaurant on the top is located on the 31st floor and completes one full turn every 75 minutes. Diners are seated 97 meters (318 ft) above ground; from up there, one has a great view that, depending on the weather, can extend all the way to the Alps. The tower was completed in 1972 and houses 180 apartments and studios as well as several office floors. It has become the symbol of the city of Mulhouse and contrasts nicely with the far older structures of the old town.
