San Pedro de Atacama: APEX (Atacama Pathfinder EXperiment)

0 -23.01°, -67.76° W
About location

Tucked into the high Chajnantor Plateau in the Andes, APEX is a place whose character is shaped by the extreme altitude and aridity of Chile’s Atacama Desert. The Atacama Pathfinder EXperiment is a 12-metre telescope built for submillimetre astronomy, detecting radiation between radio and infrared wavelengths. Its site, more than 5,000 metres above sea level, lies among other major observatories, including the ALMA array. APEX began scientific operations in 2005 and has contributed to studies of cold interstellar clouds, star formation and distant galaxies. Although associated with San Pedro de Atacama, the facility belongs to a remote scientific landscape rather than the town’s adobe streets and oasis setting.

City San Pedro de Atacama

San Pedro de Atacama occupies an oasis on the western margin of the Atacama Desert in Chile’s Antofagasta Region. Adobe lanes and low houses reflect the settlement’s long association with the Lickanantay, or Atacameño, people, whose communities developed in one of Earth’s driest regions. The whitewashed Church of San Pedro de Atacama, on the central plaza, is an enduring colonial-era landmark. Beyond the oasis, the Andes rise towards the Chile–Bolivia frontier, while the Salar de Atacama extends to the south. Nearby Pukará de Quitor, a pre-Hispanic fortified settlement, recalls the area’s earlier history.

Region Antofagasta Region

Antofagasta Region has served as Chile’s mining heartland since the late nineteenth century. Inland, the Atacama Desert gives the region its immense, arid scale, while its western edge follows the Pacific coast. Copper has shaped its modern economy: the Chuquicamata mine near Calama is among the world’s largest open-pit copper mines, and the city of Antofagasta is a major port. Around San Pedro de Atacama, salt flats, volcanoes and high Andean wetlands meet longstanding Atacameño traditions. The region is central to northern Chile’s geography as well as its industry.

Country Chile

Among the countries of South America, Chile stands out for its exceptional north-to-south extent between the Andes and the Pacific Ocean. The Atacama Desert in the north is one of the driest places on Earth, while the south reaches into Patagonia, where Torres del Paine National Park is known for its jagged granite peaks, glaciers and lakes. Chile also includes Rapa Nui, the Pacific island famed for its monumental moai statues. In Valparaíso, steep hills, funicular railways and colourful historic neighbourhoods reflect the country’s maritime past; its historic quarter is a UNESCO World Heritage Site.
