The "black triangle

of Quercy

This area located in the heart of the Parc Naturel Régional des Causses du Quercy is one of the most favorable regions in France for sky observation (outside of the mountains), particularly thanks to the low population density. Even if this classification of best sky in metropolitan France has since been questioned, many communes have been labeled “starry villages” thanks to their actions for the preservation of the night sky; in particular the extinction of public lighting in the second part of the night.

This limitation of light pollution is beneficial for the observation of the stars, but also for the nightly biodiversity. Butterflies, amphibians, bats, owls… Many nocturnal species in the territory can have their activity disrupted if light pollution is too strong. This ecosystem is fragile and requires special attention. To better understand it, evening animations are regularly proposed by various actors, in order to observe and listen to this world of the night in all discretion.

It’s high time to turn the stars back on.
