Cerro Armazones, Mountain summit in Sierra Vicuña Mackenna, Chile
Cerro Armazones rises 3,064 meters above sea level in the Chilean Coast Range, located 130 kilometers southeast of Antofagasta in northern Chile.
The European Southern Observatory Council selected Cerro Armazones in April 2010 as the location for the Extremely Large Telescope, with construction starting in 2014.
The mountain hosts both the European Extremely Large Telescope project and the Polish Cerro Armazones Observatory, advancing international astronomical research.
The site experiences cloudless conditions during 89 percent of nights throughout the year, making it exceptionally suitable for astronomical observations.
The summit underwent modification to create a platform for the telescope construction, reducing its original elevation by several meters.
