As many of the villages along the southern coast of Norway, Grimstad has a long and rich maritime history. This nautical heritage dates far back and comprises ship and boat building as well as shipping and trade. In its heyday,from 1850 to the end of the 19th century, the Grimstad region had as many as 40 shipyards. This was when the tall ships sailed the seven seas - an industry in which Grimstad played an importan role.
The maritime museum in Hasseldalen focuses on this period and provides an insight into the everyday life of a ship owner, the training of sea pilots, the building and maintenance of wooden ships and boats and how the captain navigated the ship.
