At the bottom of the Otterböte hill, there is a unique settlement of seal hunters from the early Bronze Age (about 900 BC). It consists of the remains of nine round huts, several rubbish heaps and a little well. You'll get to Otterböte through a 600 m long footpath from Hamnövägen. Sturdy shoes are recommended.
Otterböte was populated by seal hunters from the south, who came north for seal hunting in springtime. We know this due to numerous findings of potsherds found during excavations. The clay of these potsherds comes from the southern shores of the Baltic Sea; northern Poland and the island of Bornholm. The walls of the vessels also have imprints of cultivated plants, showing that they have been manufactured in an agricultural environment.
