La Sagra Observatory

La Sagra Observatory is an astronomical research facility in Puebla de Don Fadrique located at about 1500 meters elevation with four robotic telescopes for observing the night sky. The installation uses advanced technology to continuously track and document asteroids and other celestial objects.

The observatory was founded to systematically search for and record asteroids in the sky. Over the years it has established itself as a productive research center for discovering new celestial objects.

The observatory engages with the public through educational programs, offering workshops and guided tours that introduce visitors to astronomical research methods.

The site is accessible year-round, and the nearby Los Collados resort offers lodging and dining for visitors. The elevation and remote location mean you should expect variable weather conditions and limited cellular coverage.

In 2013 the observatory identified an asteroid named Duende that passed unusually close to our planet. This was one of the facility's most remarkable finds and drew global attention to its work.
