Tryvannstarnet

Historie

Tryvannstårnet is an 118-metre tall broadcasting tower near Oslo, located 529 metres above mean sea level on the summit of Tryvannshøyden hill overlooking lake Tryvann.Tryvannstårnet was built in 1962 and has an observation deck at a height of 60 metres, from which, weather conditions permitting, the view extends to the border with Sweden and Gaustatoppen mountain. The observation deck was closed in 2005 because of new fire safety regulations which would have required expensive modifications which coincided with rapidly declining visitor numbers. In the 1980s and 1990s annual visitor numbers averaged 100,000, but in the last year it was open to the public, only 25,000.There is a large underground shelter beneath Tryvannstårnet.
