Kalyon Group


Kalyon Group is a Turkish conglomerate, with major interests in construction. In 2013 it was part of a joint venture which won the EUR22bn contract to construct a third international airport in Istanbul. Other contracts include Istanbul's Metrobus system, the construction of a new stadium for İstanbul Büyükşehir Belediyesi S.K., and the redevelopment of Taksim Gezi Park to reconstruct the Taksim Military Barracks.
The company was founded in 1974 by Hasan Kalyoncu and is now run by his sons. Kalyoncu was a close friend of the former Prime Minister Turgut Özal. Kalyon was described in 2013 by the BBC as "a company which has close ties with the governing Justice and Development Party".
