There is a place in the Saint Sernin basilica in Toulouse that you cannot visit and it is a shame because it contains two sky charts dating from the 13th century. The first, badly damaged, represents an abstract view of man’s place in the universe, while the second represents the geocentric system where the earth is the center of the universe. I suggest you discover a small video (ufortunatly in french..) very well done on the subject.
Les Chemins Occitans is also access to the marvelous through astronomy. If you like walking as well as the legends of the sky, I invite you to consult the page of the hiking & astronomy weekend in Ariège.
