Tryvannsmasten

Tryvannsmasten is a major telecommunications mast situated in the Tryvann area, north of Oslo, Norway. Built in the early 1960s, the mast was constructed to enhance radio and television signal coverage across the Oslo region and surrounding areas, where the hilly terrain often caused transmission challenges. The structure rises to about 118 meters in height and is designed as a steel lattice tower, optimized for stability and wind resistance in Norway’s often harsh weather conditions. Tryvannsmasten operates as a key broadcasting point for both analog and digital radio (DAB) and television (DVB-T) signals, making it an essential part of the country’s communication network. Located near the famous Tryvannstårnet, the two towers together form the Tryvann broadcasting facility, a recognizable landmark visible from much of Oslo and the surrounding forested highlands. The site is managed by Telenor Broadcast, which maintains and operates many of Norway’s major transmission masts. While Tryvannsmasten itself is not open to the public, its presence is well known to hikers, photographers, and visitors to the nearby Tryvann Vinterpark (a popular ski resort) and Nordmarka forest area. Beyond its technical role, the mast has become a subtle symbol of modern Norwegian engineering, combining functionality, resilience, and integration with the natural landscape.
