The Costanera Center Torre 2, better known as Gran Torre Santiago (Great Santiago Tower), and previously known as Torre Gran Costanera, is a 64-story tall skyscraper in Santiago, Chile, the tallest in Latin America.[6] It is the second-tallest building in the Southern hemisphere by highest architectural feature (behind Q1 in Australia) and by highest occupied floor (after Australia's Eureka Tower). It was designed by Argentine architect César Pelli.
