The high­light of the Neapo­lis archae­o­log­i­cal area is the Teatro Gre­co, a mas­ter­piece of clas­si­cal archi­tec­ture that could accom­mo­date up to 16,000 peo­ple. Hewn out of the rocky hill­side, the amphithe­atre was con­struct­ed in the 5th cen­tu­ry BC, rebuilt in the 3rd cen­tu­ry and fur­ther mod­i­fied dur­ing the Roman peri­od. Impres­sive­ly, it staged the works of Sopho­cles, Euripi­des and the last tragedies of Aeschy­lus, includ­ing The Per­sians, Prometheus Bound and Prometheus Unbound, which were first per­formed here in his pres­ence.
