Slottsfjellet - MountainCastle

My sister lives in Tønsberg. Just upside from her house is a small hill - or mountain if you like. There was an old fortress there, dating back a 1000 years. It was also the seat of Norwegian kings. Today it is only ruins, but in 1888 to commemorate the 1000th anniversary of Tønsberg city they build a tower at the site.
