Athens - Greek authorities say they will partially restore the ruined marble theatre under the Acropolis, where the works of Euripides and other classical playwrights were first performed about 2 500 years ago.

The Culture Ministry said on Wednesday the six-million-euro programme is set for completion by 2015 and will include extensive modern additions to the surviving marble seats of the Theatre of Dionysos.

Built on the southern slopes of the Acropolis Hill, the theatre was first used in the late 6th century B.C.

It hosted the opening performances of tragedies by Aeschylus, Sophocles and Euripides, as well as Aristophanes' comedies.

A small section of the 4th century B.C. seating - which could hold up to 15 000 spectators - survives in place. - Sapa-AP
