the outskirts of the Chilean Atacama Desert, 600 km north of Santiago de Chile and at an altitude of 2400 metres. Like other observatories in this geographical area, La Silla is located far from sources of light pollution and it has one of the darkest night skies on the Earth. La Silla has been an ESO stronghold since the 1960s. Here, ESO operates two of the most productive 4-metre class telescopes in the world. Come and see this place full of astronomical history.</p> <h2>Registering for a guided tour </h2> <p>The guided tours for visitors will take place every Saturday of the year.
