Tryvannstårnet

Tryvannstårnet is the name of the 118 metre high TV Tower of Oslo, located 588 metres above mean sea level near the Tryvann lake. Tryvannstårnet was built in 1962 and has an observation deck in a height of 60 metres, from which you have at clear weather conditions a sight until the Swedish frontier. The observation deck was closed in 2005 because of new fire safety regulations that would have required expensive investments, as well as a rapidly declining number of visitors. In the 1980s and 90s, the tower yearly had around 100000 visitors, while in the last year it was open the number was only about 25000.
