Gasometer City

The 4 gas holders, known as gasometers were built in 1896 as part of the gasworks at Simmering industrial zone, Vienna, Austria. After they were closed down, the 4 historic towers were renovated, converted into apartments, shopping malls and offices and reopened in 2001. The gas that was stored in the enormous tanks was primarily used for street lights and - later - private households. When they were built, the gasometers were the largest in Europe. They are listed by the country’s heritage ministry as outstanding examples of industrial architecture.
The concept of mixed-use building creates a 24 hours occupancy and activity in the gasometers with inhabitants working, living, and entertaining.
