The Celsa colony was the first Roman settlement in the Ebro Valley. Situated in the central part of the Ebro Valley, it was one of the places chosen by the Romans to start the Romanization of the northern part of the Iberian Peninsula.
With an area of approximately 44 hectares, Celsa existed for a short period of time from 44 B.C. to 70 A.D. At that time it played an important role as a communications centre due to its location on the Via Augusta, linking the Roman province of Tarraco with the Ebro Valley.
The Roman history of Celsa began when in 44 B.C.. Marcus Emilius Lepidus, governor of Hispania Citerior, decided to found a colony in the Ebro Valley on the site of the Iberian village of Kelse. It was named Victrix Iulia Lepida.
Celsa was given the rank of a colony, the highest recognition given to a city by Rome. Celsa and Caesaraugusta were the only two colonies in Roman Aragon.
The colony had up to 4,000 inhabitants including veterans of the legions who each received a piece of land to cultivate. In the Imperial period Roman citizens took up residence.
In 36 B.C. Lepidus was exiled and the colony´s name was changed to Victrix Iulia Celsa and its indigenous name was Latinized to Augusto. In the times of Nero it began to fall into decline without signs of violence. The inevitable decline became abandonment and the earth started to cover everything without another people taking up settlement. It is not clear why it was abandoned but one hypothesis points to the proximity of the Cesaraugusta colony and others suggest the motive was that Rome imposed too many administrative obstructions on the colony.
