The Norwegian Navy's submarine base. The Barents Observer asks: Ever dreamt of having your own Arctic submarine base? For less than € 14 million you can become owner of Norway’s Olavsvern Naval Base outside Tromsø. In spite of Norway’s bid to step up its military presence in the High North, the country’s only submarine base north of the Polar Circle was closed in 2009. The abandoned naval base has been for sale since January 2011, but has only been on Norway’s most popular open market web site for a couple of weeks. The base consists of 13.500 square meters of buildings and a 25.000 square meter mountain plant, including a large dock and a deep-water berth. Included in the facilities are a fuel depot, a tunnel system and emergency power system.
