The Gasometers in Vienna are four former gas tanks, each of 90,000 m³ storage capacity, built as part of the Vienna municipal gas works Gaswerk Simmering in 1896–1899.

Between 1999 and 2001, each gasometer was divided into several zones for living (apartments in the top), working (offices in the middle floors) and entertainment and shopping (shopping malls in the ground floors). The shopping mall levels in each gasometer are connected to the others by skybridges.

Indoor facilities include a music hall (capacity 2000–3000 people), movie theatre, student dormitory, municipal archive, and so on. There are about 800 apartments (two thirds within the historic brick walls) with 1600 regular tenants, as well as about 70 student apartments with 250 students in residence.
