About this site
Pumpehuset lies along the Norwegian coast near the mouth of the Oslofjord, at a point roughly between Horten and the fjord's outer stretches. The name, meaning pump house, suggests the site takes its name from a shoreline structure historically used for pumping, a common feature along this industrialized inlet.
