Dalhalla, Sweden

Lake Siljan and its beautiful surroundings are the result of a meteorite impact which happened 360 million years ago. Dalhalla is one of only three places in the world where one can see how the natural surroundings have been formed by a meteorite.

At Whitsun 1991, Dalhalla, a previously abandoned limestone quarry, was awoken from its slumber when Margareta Dellefors, a former opera singer, discovered Dräggängarna. She had been looking for a suitable place for summer festivals and found the quarry in the woods just outside Rättvik. The vision was born.
