Las Campanas Observatory (LCO) is an astronomical observatory managed by the Carnegie Institution for Science (CIS). Located in Chile's Atacama Region, it sits about 100 kilometres (62 mi) northeast of the city of La Serena. The LCO's telescopes and facilities are positioned near the northern end of a 7 km (4.3 mi) mountain ridge. Cerro Las Campanas, situated near the southern end of this ridge and standing over 2,500 m (8,200 ft) tall, will be the future site of the Giant Magellan Telescope.
