Royal Observatory of Belgium

The Royal Observatory of Belgium is a research institute in Uccle that studies astronomy, astrophysics, geophysics, seismology, and solar physics. The facility operates specialized laboratories and continuously monitors solar activity and seismic events across the country.

The facility was founded in 1826 by Adolphe Quetelet to observe the sky and measure Earth's characteristics. In 1890, it moved to its current location in Uccle, where it continued its work with more advanced equipment and methods.

The name reflects its purpose as a place of scientific observation, and the planetarium with its large dome screen serves as the main gathering point for visitors curious about the sky. Here, you experience what astronomers study when you sit under the star maps and watch celestial motions unfold.

The site is best visited during daytime hours when the exhibition and planetarium are open and solar observation is possible. It is useful to know that the institute is located in a residential area, so arriving by public transport or checking parking options in advance is recommended.

The institute operates instruments that record thousands of earthquakes and has two asteroids named after local references. This connection between the sky above and the forces beneath the ground makes the place a special window into both worlds.
