Wiener Internationale Gartenschau 64

This decision was also aimed at eliminating a waste disposal site on part of the area, as well as removing the remnants of an extensive informal settlement known as "Bretteldorf."

On the approximately 100-hectare site, the Donaupark and a 30,000 m2 lake (named Irissee, which still exists today) was created, along with a 25 km network of roads and footpaths.

[1] As a symbol of modern Vienna, the Donauturm, Austria's tallest structure, was constructed in the northern part of the park, beginning in 1962.

This included the exhibition halls, the lake stage, the 41-meter-high greenhouse tower, the cinema, and the library with "reading hills."

However, some elements remain, such as the lake restaurant (also serves the Korean Cultural Center) and the Donauparkbahn, built by the operators of the Liliputbahn in the Prater.
