Although the Evora Roman temple is often called the Temple of Diana, it is known that the association with the Roman goddess of the hunt originated from a legend created in XVII century. Indeed, the temple was probably built in honor of the emperor Augustus, who was venerated as a god during and after his reign. The temple was built in the first century AD in the main square (forum) of Évora – then called Liberatias Iulia – and modified in the second and third centuries. Évora was invaded by Germanic peoples in the fifth century, and it was at this time when the temple was destroyed; Today, its ruins are the only traces of the Roman Forum in the city.

The ruins of the temple were incorporated into a tower of Évora Castle during the Middle Ages. The base, columns and architraves continued embedded in the walls of the medieval building.
