Legend has it that in the lair of the courtyard of the governor's house, near the entrance to the old keep of the medieval city of Aigues-Mortes, a curse fell. 

Because indeed, each summer, the heat falls and shaves the ancient stones. It overwhelms anyone wishing to venture into the castle. 

​

Then came a maze. Covering the stones, it never tires of playing with the void, welcoming gardens and shadows. 

Fortunately, this maze does not need Ariadne. He simply guides. 

The curse then lifted and coolness returned to the Mediterranean city.
