Greek Theatre of Cyrene
Jabal al Akhdar, Libya
The Greek Theatre of Cyrene was the largest and oldest of the five known theatres in Cyrene, Libya. It was built on the north slope of the Acropolis, west of the Sanctuary of Apollo and was originally built as a standard Greek theatre, probably in the late sixth century BC. The structure underwent several phases of renovation and was eventually converted into a Roman amphitheatre in the second century AD.
