Zaha Hadid was selected to design the building in November 2004 and it became her first built tower.[2][3] It is intended to interact with other landmarks of the city including the Château d'If and the basilica of Notre-Dame de la Garde, which stands taller than the tower on a rocky outcrop.[4] Built by Vinci subsidiary GTM Construction,[5] the building has 20 lifts to service its 33 floors[6] and was completed in September 2011.
