The teatro greco, the “Greek theatre” is one of the most celebrated ruins in Sicily. It is built for the most part of brick, and is therefore probably of Roman date, though the plan and arrangement are in accordance with those of Greek, rather than Roman, theatres; . With a diameter of 109 metres , this theatre is the second largest of its kind in Sicily (after that of Syracuse); it is frequently used for operatic and theatrical performances and for concerts.
