Mannesmann Tower, Steel lattice tower in Vienna, Austria.
The Mannesmann Tower was a steel lattice structure with a triangular cross-section that rose approximately 150 meters high. Its entire construction relied on seamless tubular steel components joined together without traditional welded seams.
The tower was built in 1955 as a gift from Mannesmann AG for the Vienna Trade Fair to showcase the company's innovative steel manufacturing capabilities. It remained on the fairgrounds until its demolition in 1987.
The tower served as a symbol of post-war industrial advancement in Vienna, representing the technological progress of the 1950s construction techniques.
The structure served as a communications hub, supporting radio and cellular transmission across the fairgrounds area. Visitors could view it clearly from various points within the exhibition grounds where it stood as a visible reference point.
Neon lamps illuminated the entire structure at night, creating a distinctive glowing presence across the fairgrounds. This lit appearance made it a recognizable symbol of the exhibition during the 1950s and 1960s.
