Following the footprint of the black currant, our research begins with its history and cultivation in the Peloponnese and the Ionian Islands regions. We focus on Aigio, a Greek city with a privileged geographical position on the trade maps. With the first reference of the currant from ancient times, we trace its journey to the present day. Over time, it has experienced both prosperity and hardship. The trade of the currant in Aigio occurred along the coastal front, which led to the growth of the local port and railway station. During its peak, the currant was exported to ports such as London, Trieste, Odessa, Marseille and Amsterdam and to the mainland of Europe making the 19th century the “raisin century” for the Greek economy. Despite its significant position in trade worldwide, its demand went through periods of fluctuations. This caused disruptions and hardship to the economy and society, thus, leading producers to an impasse which resulted in the start of organized protests.To resolve the issues related to the black currant, a number of institutions were established such as the Raisin Bank, the Autonomous Raisin Organization, associations, and cooperatives like Panegialios Union of Cooperatives. In the late 19^th and early 20^th centuries, in the port area, construction of industrial buildings was being developed, mainly for raisin processing. These were rectangular structures, typically made of stone or, more rarely, of concrete.  At the present time, some of these buildings still exist in Aigio and their value dictates their preservation and reuse, forming the basis of our interest in this subject.
