Fur Museum is a museum of local natural and cultural history.In the area of natural history, the museum concerns itself with geological aspects of the County of Viborg, with a special emphasis on the moler clay (a diatomaceous earth) in the western section of the Limfjord. The museum deals with cultural history, ethnology and archaeology on the island of Fur. It describes the area''s special landscape and subterranean world, telling a story that ranges from the tropic moler-clay sea to the arctic climates of the Ice Age, when the vast glaciers shaped the region that would later become Denmark. The museum serves as a guide, helping visitors to experience these fantastic landscapes, and arranging a number of activities including nature walks, lectures and nature-related workshops. The museum houses a unique fossil collection of international stature. The collection relates the 55-million-year history of life in the moler-clay sea and describes the petrified sea-bed itself. The layers of ash contain information about the powerful forces that tore Greenland away from Norway 55 million years ago and created the large volcanoes that spewed ash all across the area now known as Europe. The moler-clay area is the only place on Earth where the '"birth certificate'" of the North Atlantic has been preserved for posterity.The many different exhibitions at Fur Museum allow visitors to experience the past. The island''s cultural history reveals it to have constituted a desirable habitat ever since the end of the last Ice Age. Wherever you dig on Fur, the past can be found in the soil. The exhibitions at Gammelhavn and Museumsgården describe human life on the island down through the ages. Here, visitors can learn about the fishermen-farmers who have made their living on Fur ever since the Middle Ages - sometimes setting off from the island in small boats to trade throughout the entire Baltic region.
