Exploration #60. The production of the gas in this vast area started in 1905. The gas was initially produced from the distillation of fossil carbon and from the 1970 by means of a cleaner and more efficient process. The gas was then stored in big gasometers ready to be pumped the city network. The production of the gas stopped in 1994: the plant was demolished but the two big gasometers and connected compressor rooms were saved.
