Chile Flag Europe Flag Cerro Armazones E-ELT Observatory, Chile

Cerro Armazones is a mountain located in the Sierra Vicuña Mackenna of the Chilean Coast Range, approximately 130 kilometers (81 miles) south-east of Antofagasta, Chile. It is located in a privileged zone for optical astronomy because it has 89% cloudless nights a year.
On 26 April 2010, the European Southern Observatory Council selected Cerro Armazones as the site for the planned European Extremely Large Telescope (E-ELT). The mountain top was blown away on 2014 June 19, marking the start of the construction work. The E-ELT will be the largest optical/near-infrared telescope in the world: the world’s biggest eye on the sky. The 39-meter primary mirror stretches over almost half the length of a soccer field. More… Nearly two years later the private road leading to the summit of Cerro Armazones has been completed on the concession land offered by Chile.
