The Theatre of Herodes Atticus, also known as the Odeon, is a Greco-Roman theatre built in 161 AD.
It is named after an affluent Greek-born Roman senator, Herodes Atticus, who constructed it in commemoration of his wife, Regilia.
Able to seat up to 5,000 people, the Theatre of Herodes Atticus was mostly used for music shows and festivals, a function which the now restored structure still performs today.
