The world\u2019s biggest shell banks were formed near Uddevalla around 10,000-11,000 years ago.\u00a0 At the time the edge of the inland ice sheet was sitting across lake V\u00e4nern. The ground was heavily weighed down beneath a sheet of ice several miles thick; once the ice had melted away the ground began raising fast at a rate of at least 7cm\/year. At its highest the sea level was 145 metres above its present-day level, equivalent to almost at the top of the Uddevalla bridge pylons.<\/p>\n
The meltwater from the ice sheet rushed westwards into a cold and briny Arctic Ocean. This resulted in strong saltwater currents being forced eastwards inland beneath the rushing meltwater. The currents strengthened as they passed through the narrow straits where Uddevalla lies today. This turbulent marine environment provided the ultimate milieu for both sessile and free-swimming aquatic animals. Phytoplankton and zooplankton provided nutrition for filter feeders such as mussels, barnacles, ascidians, sponges, bryozoans etc. These in turn were eaten by snails, crustaceans and fish. A total of 23 shell banks were formed in the Uddevalla area with a total volume of 1 million cubic metres. The largest shell banks were formed at Porsen-\u00c4lje (20m), Br\u00e4cke-Kur\u00f6d (13m), Samner\u00f6d, and Kapelle.<\/p>\n

<\/a><\/h2>\nThe white shell deposit hills surrounding the shell bank museum and the pond at Br\u00e4cke consist largely of Hiatella arctica<\/em> and giant acorn barnacles. They also contain considerable amounts of sea mussels and sea snails. Overall, a total of 103 aquatic invertebrate species have been found in the Br\u00e4cke-Kur\u00f6d shell banks. Most of these are so-called glacial species; they lived here when this was an arctic ocean and were formed over a period of 200-1,000 years. Scientists who have explored this fauna include Carl von Linnaeus in 1746, J Gwen Jeffreys in 1862, Hjalmar Odhner in 1927, and Anders War\u00e9n in 1969.<\/p>\n In addition, excavating the shell banks for the purpose of manufacturing chicken feed revealed several species of aquatic mammals, predominantly bones from ringed seals \u2013 the smallest of our native seal species \u2013 and also from killer whales, belugas, humpbacks, bearded seals, and polar bears. The oldest avian bones ever found in Sweden were discovered in the Samner\u00f6d shell banks in 1969. These were bones from eider ducks believed to be around 10,700 years old.<\/p>\n When the town of Uddevalla celebrated its 500th anniversary, the council took the opportunity to create the Shell Bank Museum. The museum was opened on 26 August 1998 by the King and Queen of Sweden.<\/p>\n On display at the Shell Bank Museum are collections of shells from Bohusl\u00e4ns Museum, donated by Robert Thorburn in the late 19th century. You can also view models and animations showing the melting of the ice sheet and the isostatic uplift of the land.<\/p>\n A series of watercolours by Cia Callermo illustrate the species-rich and lime-loving flora. The biodiversity of insects is represented in the form of a selection of mounted butterflies and moths.<\/p>\n Here you will be able to sample the rich and varied cultural and industrial history of the shell banks. The shell banks became a topic of heated debate between those wanting to preserve their unique structures and those wishing to exploit them. A recorded radio interview with factory owner Ragnar Steene, first broadcast in 1937, is available for listening. During a period of time in the 1950s and 60s, the motocross Swedish Championship and World Cup were held at the Kur\u00f6d banks.<\/p>\n The Kur\u00f6d, Br\u00e4cke and Samner\u00f6d shell banks have been nature reserves separately for over 50 years. In 2010 a large nature reserve was created that covers all three, under the name of Kur\u00f6d nature reserve. In 1997 a programme of extensive felling, clearing and fencing was commenced to enhance the mosaic nature of the landscape with its rich biodiversity. Since 2004 this has been home to a herd of 10 or so cows and their calves. Their grazing and treading the land with their cloven hoofs have given the flora a fantastic boost.\u00a0 Successful nature conservation requires commitment, enthusiasm, cash, manpower, patience, and grazing animals (cattle). Together, Bohusl\u00e4ns Museum, Uddevalla Town Council and V\u00e4stra G\u00f6taland County Council have achieved amazing results at the Kur\u00f6d shell banks nature reserve.\u00a0 Today these efforts can be enjoyed by our visitors all year round. Having said that, the shell banks are probably at their most beautiful at the end of May and beginning of June.<\/p>\n The shell bank trail is a walking trail in the Kur\u00f6d nature reserve. It\u00a0starts at the museum and runs in parallel with the Bohus Route; it is marked with the shell bank museum logo (a red plaque). The trail will take you past a series of information boards that outline how the banks were formed over time and describe von Linnaeus\u2019 visit to the site, as well as settlements that date back to the early Stone Age, around 11,000 years ago, amongst other topics. There are also a number of derelict sites, some of which have intact stone foundations with ornamental trees, plants, cairns and stone walls. The trail also passes through large thickets of hazel, past a waterfall and down into the \u2018Kur\u00f6d cauldron\u2019 where you\u2019ll be able to view the beehives. The trail then runs up the Kur\u00f6d hills, from where the views over Byfjorden and Uddevalla bridge are magnificent. It then descends the hill on the other side, passing a hayfield which is hand-mown using scythes in July and August each year and adorned with old-fashioned hayracks. The slopes of the Kur\u00f6d hills are home to the most species-rich flora of plants and grasses.<\/p>\n From 13 June to 17 August\u00a0<\/span><\/p>\n You can always visit the shell banks, and go the shell bank\u00a0trail even if the museum is closed.<\/p>\n Address:<\/span><\/strong> Kur\u00f6dsv\u00e4gen 1, Uddevalla, Sweden The world\u2019s biggest shell banks were formed near Uddevalla around 10,000-11,000 years ago.\u00a0 At the time the edge of the inland ice sheet was sitting across lake V\u00e4nern.
