"Fokuskvartalet" (4 of 7)
The Focus Cinema opened in the early 1970s and was designed by the architect Gunnar Bøgeberg Haugen, who won an architecture competition in 1966. The concrete shell measures 12 centimetres in thickness, with four supporting points, and is inspired by a hyperbole paraboloid. The principle for this type of construction was developed by the Spanish architect Felix Candela. Therefore this kind of structure is often referred to as a Candela-shell. Even though the Focus Cinema was torn down in 2004, the roof shell structure was conserved and re-emerged as the town library.
