This Roman theater, one of the best-preserved Roman ruins in the world, was built by Agrippa (Augustus’ son-in-law) in 18 b.c. to house an audience of 6,000 people. Modeled after the great theaters of Rome, it was constructed using dry-stone methods (a remarkable achievement). During the reign of Hadrian (2nd century a.d.), a tall stage wall was adorned with statues and colonnades. Behind the stage, today’s visitors can explore excavations of various rooms. From the end of June to early July, you can also enjoy a season of classical plays.
