The name of our town becomes from the Islamic Ocupation. A Berber tribe known as "Miknesa" settled on the banks of the Ebro and eventually evolved into naming the present town of Mequinenza. Mequinenza before the flooding for the Ribarroja dam was located on the banks of the Ebro, inside the castle walls.
Over the years, the town of Mequinenza has been filling history books until the year 1970, when the last paragraph was written, after being flooded by the Ribarroja dam. From that moment, a new town resurfaces near its old enclave opening a new book of its History, but always to the slopes of its hill, that at the moment continues crowned by its castle, fortress very dear to mequinenzanos denominating it "The Castell of Mequinensa. "
The castle was built between the XIV – XV century, its the most emblematic building in Mequinenza, it’s been defeated at times and reappers every time more strong and nobility.
In his time travel was a phoenician tower, arabic fortness, Montcada’s Palace, Medinaceli’s Ducal house, French conquest, Fernando’s VII Crown property, military fortness, the major figure of the civil war and finally after been witnessed so much history, re-emerge with a radiant beauty thanks to a preservation and restoration works from a private foundation.
The castle is like the viewfinder eye that controls the village, wrapping it in its skirts to protect it, perhaps for that reason the mequinenzanos feel so proud of him.
The economy of Mequinenza has been based on the agriculture and very mainly with the lignite mining. This last activity has disappeared, since since the Mequinenza Dam was realized, its economy has been focused on the generation of electricity, in the sports field and the increase of the irrigations in the rustic zones.
