Sandvik has been an important harbour, especially when shipping limestone from Öland both to Swedish harbours and abroad. On the quay there is still an electric rock crane. The coast north of the harbour is still characterised by the quarries since limestone for building purposes was one of the few products that, the otherwise poor, northern Öland could produce and sell. There are still active quarries, but stone shipping from Sandvik harbour ended in the 1960's. Above the harbour, the Dutch-type windmill is clearly visible. Sandvik windmill is not only the largest windmill on Öland, but is also said to be the largest windmill in northern Europe. As it is clearly visible from a long distance it has become a landmark in the flat landscape and a symbol of Sandvik.
