CAOS Centro Arti Opificio SIRI
In 1905, the ironworks closed and from 1910 the warehouse was used for metalworking and chemical processing, mainly for war purposes. In 1925, on the initiative of Luigi Casale, Società Italiana Ricerche Industriali (SIRI) was founded, active in the production of synthetic ammonia and chemical products and in the study and exploitation of new industrial processes in the chemical, physical and mechanical fields. From 1945 there was a progressive decline in production and workers, leading to its final closure in 1983. Ownership of almost all the former factory was taken over in several stages from 1997 to 2002 by the Municipality of Terni and thanks to a restoration and requalification campaign, it has been home to CAOS, Centro Arti Opificio Siri since 2009.
The recovery of the industrial space of the former SIRI chemical factory, restored and redeveloped, is an exemplary case from an Italian point of view of the reconversion of disused industrial areas for urban use. From a chemical factory to a factory of culture, the backbone of a new creative city was established, an emblem of the process of redefining Terni as a contemporary city.
Some external spaces have maintained their original layout, such as the access avenue, the central widening of the original housing system and some infrastructural elements, including the water intake system for the power stations. All the other pre-exiting buildings are currently used for cultural activities, making it highly innovative. With its 5.600 square metres of space dedicated to cultural development, CAOS is an open and flexible centre for the production and enjoyment of the arts, consisting of permanent exhibition spaces. These include the Aurelio De Felice Museum of Modern and Contemporary Art and the Archaeological Museum of Terni, a vast area dedicated to national and international temporary exhibitions, the Sergio Secci Theatre, Arealab dedicated to educational and creative workshops, ateliers for artistic residences and productions, a specialised library, a video room and a café/restaurant, FAT, with events taking place until late at night.
