The operation of the Museums' Network and the coordinated actions of PIOP in all its buildings contribute significantly to: a) the promotion of Greek cultural heritage and the interconnection of culture with the environment and sustainable growth, b) the promotion of the traditional crafts and the intangible cultural heritage of Greece, supporting employment, economic and tourist activity and the general development of local communities, and c) the creation of areas of culture and life-long learning by organising cultural, scientific and educational actions.
