Considered a World Heritage Site by UNESCO since 1986, the Évora Roman temple is one of the largest and best preserved in the Iberian Peninsula. In the 5th century, barbarian peoples invaded the city and destroyed part of the monument. It then underwent a restoration process coordinated by the Italian architect Giuseppe Cinatti. It preserves its complete base; the stairs are in ruins and it has 14 columns built in marble and gran-ite. This Roman temple, known to many as the Temple of Diana, takes this name erroneously. This associa-tion with the Roman Goddess of the Hunt originated with a legend in the 17th century. Only later, in the 1980s and 1990s, was it discovered that the temple had been dedicated to the emperor Augustus. It was renamed Évora Roman Temple. It was classified as a National Monument in 1910.
