Bordeaux Observatory

Bordeaux Observatory sits on elevated ground overlooking the Garonne River with multiple scientific buildings spread across its grounds. The site brings together observation instruments, laboratory spaces, and administrative areas designed for conducting astronomical research.

The facility began operating in 1878 under the direction of Georges Rayet with a focus on systematic astronomical observations of the sky. It was established as a modern research center dedicated to gathering scientific data and advancing knowledge of the heavens.

The meridian building houses a collection of 19th-century astronomical photographs and handwritten celestial maps that document observations made from this location. Walking through the corridors, you can see how researchers carefully recorded and preserved their findings about the night sky.

When visiting, keep in mind that the grounds have some uneven terrain, so sturdy footwear is advisable. Guided tours happen regularly, and you should check in advance which parts of the facility are open to the public.

The grounds feature a converted World War II radar system from Wurzburg that was repurposed into a radio telescope for astronomical research after the war. This instrument shows how scientists adapted available technology to advance their observations of the cosmos.
