Haven't found it, yet, but here is a site which shows the names of the largest Chilean Atacama Desert installations, as a starting place. I will continue to look. I'm very interested in finding out about this, myself, now you've mentioned it. Northern Chile, Tropic of Capricorn, I need to get a clearer look!
I'll continue to look for more on this:
Observatories in Chile

The skies of northern Chile are considered the best in the world for astronomy. A growing number of Chileans and foreigners are visiting the various facilities to observe the skies over the last decade. However, most of the observatories positioned in the Norte Chico (Third and Fourth Region), since the 60s have been for scientific use only, leaving very little for the tourist. In the mid-90's, a study by European scientists from the European Southern Observatory (ESO) decided to build a new and more sophisticated observatory, this time in the Norte Grande (Second Region), for highly scientific purposes, which will determine and reveal many mysteries in space. The place chosen was Cerro Paranal Observatory, considered the largest in the world.

Stumbling Towards First Light
Why has Chile, a country riven by inequality and political conflict, become a global sanctuary for the long science that drives astronomical discovery?

. . .
Few countries have been more successful at attracting this kind of capital than Chile. The GMT is one of three colossal observatories currently under construction in the Atacama Desert. The $1.6 billion Extremely Large Telescope, which will house a 128-foot main mirror inside a dome nearly as tall as the Statue of Liberty, will be able to directly image and study the atmospheres of potentially habitable exoplanets. The $1.9 billion Vera T. Rubin Telescope will use a 3.500 megapixel digital camera to map the entire night sky every three days, creating the first 3-D virtual map of the visible cosmos while recording changes in stars and events like supernovas. Two other comparatively smaller projects, the Fred Young Sub-millimeter Telescope and the Cherenkov Telescope Array, are also in the works.
Chile is already home to the $1.4 billion Atacama Large Millimeter Array (ALMA), a complex of 66 huge dish antennas some 16,000 feet above sea level that used to be described as the worlds largest and most expensive land-based astronomical project. And over the last half-century, enormous observatories at Cerro Tololo, Cerro Pachon, Cerro Paranal, and Cerro La Silla have deployed hundreds of the worlds most sophisticated telescopes and instruments to obtain foundational evidence in every branch of astronomy and astrophysics.
By the early 02030s, a staggering 70 percent of the worlds entire land-based astronomical data gathering capacity is expected to be concentrated in an swath of Chilean desert about the size of Oregon.

It's imperative for anyone interested in this fascinating subject, take the time to look in Google images for each name of a telescope project mentioned, as each one is beyond description! All "Ones of a kind!"

Forgot to thank you, Permanut, for your post. I tore off to look for more, and completely forgot to thank you for your comment!
