Visits to ESO Sites
This page is available in Spanish on our Chilean web site.
ESO is actively monitoring the fast development of COVID-19. To ensure the safety of its staff and the public, ESO has decided to take the precautionary measure to suspend public visits to ESO’s La Silla and Paranal Observatories in Chile until further notice.
We recommend you check our website regularly as any new changes will be communicated on this page.
If you have questions we kindly invite you to contact us through the following email email@example.com.
For media visits, we invite you to read the information in the corresponding section.
