Description:
The Cavern Hall is an enormous project that would have completely destroyed the proportions of the little town of Gjøvik if it had been built above ground. Norway has a long tradidion of rock tunelling and the Cavern Hall is the most advanced construction of its kind. The unsupported 60-metre roof span was the largest in the world at the time of consruction.
The interior subdivision into geometric shapes of varying sizes provides interesting visual impressions of space. The rock walls are reinforced for greater safety with steel nets sprayed with concrete and painted dark grey. They are covered with crushed glass, to provide a surface that heightens the impression of a fairytale underworld. This is enhanced by the halogen lighting effects, interspersed with brilliant sun spots. The Cavern Hall is a good exemple of energy conservation, since, once it has been warmed up, the temperature inside the mountain will remain at a stable 8 degrees Celsius all year round. Minimal maintenance in required because the building is protected from the elements.
