Istanbul Sapphire, or Sapphire, is a skyscraper, and as of 2011, the tallest building in Istanbul and Turkey, located in the central business district of Levent. It will relegate to the second spot upon the completion of the Diamond of Istanbul triple towers, located in the nearby central business district of Maslak. It is the country’s first ecological skyscraper. Sapphire rises 54 floors above ground level, and boasts an above-ground roof height of 238 meters (the building has an overall structural height of 261 meters including its spire, which is part of the design and not a radio antenna.) It is a shopping and luxury residence mixed-use project by Biskon Construction (a subsidiary of the Kiler Group of Companies.)
