The concept of a museum takes on a different meaning in Greece. From Athens' stunning Acropolis museum to a village's one-room folklore museum or a monastery's natural history museum, each has a story to tell that bears directly on the village, city or region it belongs to.
Not all might be first-class organizations, but the beauty lies therein, reflecting the simplicity and pride of the local people who have worked hard to respect that culture, traditions and memory of their homeland in one way or another. Greece's eclectic museums, therefore, contribute wholeheartedly to preserving the social fabric of a place.
By definition, this makes them eco-friendly in what they stand for, as the museums help safeguard the local identity and contribute to sustainability. You would do well to visit the museums in each area you visit!
