The Gulf of Thermaikos, located in the northwestern part of the Aegean Sea, between the seashore of Pieria and Chalkidiki peninsula and dominated by Mount Olympos, is representing within the project another type of geographical entity. Areas with very diverse characteristics are scattered around its waters, from the wetlands on the rivers estuaries to the urban settlements of Thessaloniki and its surroundings and finally to the high slopes of Mikro and Megalo Emvolo caps, the saltworks of Angelohori and the fisheries port of Michaniona. The historical importance of the site is documented since the antiquity, and is based on the archaeological evidence of prehistoric settlements, antique colonies, harbours, sanctuaries and forts of the last two centuries. The traditional production and trade of salt, tobacco, silk cocoons, woolen textiles and leather manufacture developed during the last quarter of the 19th c. in a mostly steamdriven industry of textiles and leather, food and beverages, brick and tiles and in the tobacco commercial treatment. The modernization of the infrastructure in transportation and port premises and the networks of water and gas supply supported the industrial development in the Gulf area. The Ephorate for Modern Monuments of Central Macedonia (Ministry of Culture) is promoting the project, having already carried out research and developed activities for the conservation and enhancement of industrial heritage sites. The local part of the project is focusing the planing and implementation of the “Ecomuseum of Thermaikos Gulf” and involves several local institutions including the universities, the municipalities, private and state archives, NGOs, public and private authorities.
