At Rosenlund Banks, erosion has caused the south shore of Lake Vättern to plunge dramatically into the water, forming a 35-metre high precipice that extends for two kilometres and is visible from far away. This is one of Sweden’s most famous ice age deposits and a highly characteristic element of the landscape.
The precipice provides a natural breeding site for a large colony of sand-martins, while kingfishers breed in a nearby gully. There are excellent places for watching migratory birds in the spring and autumn. Broad-leafed trees grow on parts of the scree and precipice. There are also five venerable giant oak trees nearby, with circumferences between three and seven metres!
Interesting finds have been made by marine archaeologists in Huskvarnaviken bay, east of the precipice. The bay is home to an impressive cairn, and other finds including a sword and a necklet dating from the Bronze Age are on display at Jönköping County Museum. A model of the cairn and a number of items can also be found at Kruthuset (Huskvarna Village Museum).
