Did you know that you can observe the stars, the planets, and even the Sun… without leaving Namur?

The Antoine Thomas Astronomical Observatory, located in the heart of the University of Namur, invites you to discover the wonders of the sky, day and night.

A place steeped in history and looking toward the stars

Located on the very spot where Jesuit priests used to observe the sky in the 19th century, the observatory combines tradition and modernity. Today, it is equipped with state-of-the-art instruments, including one of Belgium’s largest solar telescopes, which allows visitors to observe the Sun in complete safety.
