Turning Torso in Malmö

Turning Torso is the tallest skyscraper in Sweden and the Nordic countries, situated in Malmö, Sweden, located on the Swedish side of the Öresund strait. Upon completion, it was the tallest building in Scandinavia.
The building was designed by the Spanish architect Santiago Calatrava and officially opened on 27 August 2005.
The tower reaches a height of 190 metres (623 feet) with 54 stories.
The building is constructed in nine segments of five-story pentagons that twist as it rises; the topmost segment is twisted ninety degrees clockwise with respect to the ground floor. Each floor consists of an irregular pentagonal shape rotating around the vertical core, which is supported by an exterior steel framework.
