"Lanificio Gruber" in Terni: an ancient artefact of the industrial archaeology, across time of abandon and the new incentives of sustainable regeneration

The "Lanificio Gruber", is an ancient woolmill located in Terni, an Italian industrial town, called "the little Manchester", for its deep involvement in the industrial economy, with a weapons factory, an important steel mill and other textile manufactures. The historical frame of the "Lanificio Gruber": its activity started in 1846, and end in 1939, that is very early compared to the life of the other factories, this is why the area has always be seen as a void inside the town, without any valorization, and completely left to a state of abandon. The paper will present an architectural project that concern a complex intervention degree: in fact, it comprehends an architectural scale, in considering the ancient buildings of the factory, but it can also be seen as a more extended project, which involves the green area around the buildings and its relation with the territory around, according to its particular position, between the city center and the industrial area, directly related to the Nera river, and - in an even more ample scale - in connection with the extremely beautiful landscape of the "Valnerina", with its famous "Marmore waterfall". The technical aspects of the buildings are been analyzed with the laser scanner technique for the metrical and topographical surveys; a multilevel approach has been used to combine the research data into three future scenarios of development: inhabitants participation, valorization of the historical aspects (as part of the "minor heritage"), potential connection with the surrounding landscape.
