Allianz Tower
Allianz Tower is currently one of the tallest buildings in Italy at 209m and with its 50 floors is the tallest to the roof. It was designed by the Japanese architect Arata Isozaki and Italian architect Andrea Maffei.
The tower is composed by 8 modules by 6 floors each one. The facade is made with a triple glass unit slightly curved to outside. The vertical succession of rounded forms creates a feeling of slight vibration of the volume of the building as it rises upward. Elevations of the short sides are fully glazed and show the mechanical series of 6 panoramic lifts going up and down to the various floors of the building.
The idea of an endless tower can be compared to previous ambitions of other artists as Constantin Brancusi, for example, who in 1937-38 installed one of his endless column of Targu-Jiu in the park to create repeatable systems indefinitely.
