This was the first discovered rock art site of Ermites assemblage despite its hard access. The shelter is 8 m over the ground and currently two vertical ladders allow the access to researchers. Most of these pictographs were painted on the ceiling of this shallow cave. Red and white pictographs are preserved here, most of them affected by a blackish crust that veil them. Seventy figures have been recorded, some of them taking part in a hunting scene of horses.
This shelter is closed to the public because of its difficult access and for preservation of paintings.
From Ulldecona should take the T-331 road towards Tortosa for about 2 km to the turnoff that leads to the Ermita de la Pietat. The vehicle can be left in the parking lot. This rock art assemblage have an interpretation center from which guided tours are organized.
