It is one of the most extraordinary prehistorical art locations in the world, since it bring us to the true Paleolithic times. The huge set of engravings in rocks along the river, the biggest in Europe and likely the biggest in the world, set in a semi deserted area, create a beautiful natural setting undisturbed by progress. The engravings date back to 22,000 to 10,000 years BCE.
Many scientists now believe that the carvings done in Paleolithic times were mostly done at open air and not in caves but were destroyed by time and construction.
The local shepherds have also done some paintings in some rocks signs of the times.
The park is currently a Unesco World Heritage Site
A few years ago, people preparing the building of a new dam, discovered, in river Coa's slopes some strange carvings. Following studies confirmed the existence of a large collection of Paleolithic figures, some of them dated from about 20 000 years ago.
The works were stopped, and the area was preserved, and declared by UNESCO as World Heritage.
It's not an easy job, visiting the place. You must book in advance, and may choose to use a jeep to follow the 20 kms of trails, or to use a boat to see it from the river, in a less detailed but more comfortable way.
Small village with less than 500 inhabitants, located a few kilometers south of Foz Coa, it has to see the palace of the viscount of Almendra, and a Romanesque church.
