"High Fires" are a very old tradition: in the Middle Ages they served as a warning method in case of an imminent danger! In 1988 the idea of conforming a "chain of light" was resumed and at first go hundreds of fires burned. Every year, herdsmen and women, mountain regions associations, solidarity and environmental movements from many alpine states, repeat this alpine overlapping event. With these visible "High Fires" will be set an impressive symbol for the conservation of the natural and cultural legacy of the alpine regions as well as against the destruction of alpine ecosystems. "High Fires" should encourage us to take the future in our hands and so to engage ourselves in sustainable development.
