The Town Hall of Coristanco, being inland, has very different attractions as far as astronomical observation is concerned. In this case, the Fontecova Lagoon, in Cuns, should be highlighted. This lagoon has an area of 175 by 125 meters at its furthest points.
Its origin is curious, as it arises when the place that was used for the extraction of kaolin was occupied by water until it reached a depth of thirty meters at some point. The reflections of the night sky on the water speak for themselves, so the combination of low light pollution with the environment itself is unique.
