Botnhamn is an old farmyard mentioned in historical writings around 1370 under the name Stufunes. There are several archaeological discoveries from the Stone Age, Iron Age, and Middle Ages and the most known is The Silver Treasure of Botnhamn from approximately 1000 AD. The farmyard has probably been part of a chiefdom located on both sides of the outer Malangen Sound. In the 17th century, Botn was a bailiff estate in Balstad jurisdiction. Through the establishment of trading activity at the end of the 19th century, Botnhamn grew to become a center in Hillesøy municipality.
