Gehry Tower is a nine-story building constructed by architect Frank Gehry; it is located at the Steintor, Goethestraße 13a, in Hanover, Germany. The building was commissioned by the city-owned Hanover Transport Services (üstra), for whom Gehry also designed a bus stop in the city.Constructed of stainless steel, the tower is memorable for the noticeable twist in its outer façade on a ferroconcrete core, making optimal use of the relatively small piece of ground on which it is located.
