Istanbul Sapphire, or Sapphire, is a residential skyscraper located in the central business district of Levent in Istanbul, Turkey. It was Istanbul's and Turkey's tallest skyscraper between 2010 and 2016, and the 4th tallest building in Europe when its construction was completed in 2010. Sapphire rises 54 floors above ground level, and has 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. Designed by Tabanlıoğlu Architects, it is a shopping and luxury residence mixed-use development managed by Kiler GYO. It is also the country's first ecological skyscraper. As of 2020, Istanbul Sapphire is the 4th tallest skyscraper in Istanbul and Turkey, behind the 284-meter-tall twin towers of Skyland İstanbul located adjacent to Türk Telekom Stadium in the Seyrantepe quarter of the Sarıyer district, on the European side, and the 280-meter-tall Metropol Istanbul Tower in the Ataşehir district on the Asian side of the city.
