During the Spanish Civil War, the village of Graus served as a fairly important local commercial center with 2,600 inhabitants around 1936.

There are also uninhabited villages: Bafaluy, Cancer, Erdao, Fantova, Grustán, Pano and Torruella de Aragón.

The first population in Graus is dated from the Paleolithic as is evidenced by the remains found at the site of "Las Forcas" close to the Morral Rock.

In 1223, Peter II of Aragon granted the town with the title of "Very Noble and Very Old Village of Graus", which retains today.

The Valencian saint was preaching here with great success, giving in appreciation of all done by the town a crucifix which is preserved and venerated in the local church.

The main festivities of the town are dedicated to Vincent Ferrer and the Holy Christ, celebrating that visit and his appreciated donation.
