Sternwarte Simplon-Adler

The Sternwarte Simplon-Adler is an astronomical observatory located on Simplon Pass in Switzerland. It contains professional telescopes that enable visitors to observe stars, planets, and other celestial objects in detail.

The observatory was established to take advantage of the excellent viewing conditions at this high elevation. The Simplon Pass itself became a major route connecting Switzerland and Italy in the early 1800s.

The observatory brings together people interested in the night sky through shared observation sessions and talks about astronomy. Visitors find a welcoming place to discover how the stars and planets move across the seasons.

Bring warm clothing since temperatures at this elevation are significantly cooler than in the valley below. Clear nights offer the best viewing conditions, so check weather forecasts before planning your visit.

On clear nights, observers can see the Milky Way with remarkable clarity from this location, something rarely visible from lower elevations. This exceptional view of our galaxy is one of the main reasons the site was chosen for serious astronomical work.
