In Greece, the appreciation of industrial buildings is relatively recent, with the legal authorities having recognized their historical value by listing them as monuments. Nineteenth century industrial buildings can be identified as cultural monuments of the past, as well as assist in the reconstruction of urban landscapes. Additionally, individual initiatives, organized by volunteers, present the necessity for documentation through relevant research projects. The reuse of industrial buildings for cultural activities has lately become a common practice. In Athens, a large number of buildings dated to the industrial revolution and that present historical and architectural features worthy of being preserved have been recorded. Following the philosophy of smart cities, this paper presents a digital inventory of the industrial buildings located in the historical center of Athens; many of which have recently been adapted to host cultural activities. Τhe use of smart technology, by creating a digital application for smart phones, will provide access to a continuously enriched registry, via interactive maps. This initiative will promote the buildings’ past and present use and, moreover, the creative concept of their multiple functions. The suggested model of cultural management is applicable to every industrial building in Athens.
