Aosta Valley Astronomical Observatory

Aosta
Aosta Astronomical Observatory hidden in the Saint-Barthélemy Valley.
  • The planetarium show, tours, and special events at the observatory are all in Italian only.

  • The nighttime guided tour includes the observation of the sky with the naked eye—with commentary by your guide using a laser pointer—as well as through telescopes.

  • Temperatures plummet in the evening at this high altitude, so wear warm clothing and bring extra layers.

  • There’s a 5-minute walk to the observatory along an unlit gravel driveway, so bring a flashlight or headlamp.

  • The site is fully accessible to visitors in wheelchairs.
