482.2 TITLIS Tower
The 56-meter-high Titlis antenna tower was built in the mid-1980s as an element of telecommunications infrastructure. Due to its exposed location over 3,000 meters above sea level, the tower is anchored deep into the limestone mountain by a concrete structure and built with an almost filigree steel framework. The tower is defined by this existing steel structure, which we extend and develop with the addition of two horizontal volumes and four vertical circulation towers. The external load-bearing structure allows the interiors of the two new volumes to remain entirely column-free. The existing concrete base has been enlarged to create an entrance and orientation level, bringing together visitor access, technical areas, and a garage for trail grooming vehicles. The underground tunnel, built at the same time as the original tower, provides a direct, weather-protected connection from the tower to the mountain station; It also gives access to the glacier cave and serves as a technical link — an infrastructural umbilical cord within the rock. In contrast to the raw materiality of the tunnel, a reflective steel band guides visitors from the mountain station towards the tower.
