Alexander's Roman Theater is located1.5 kilometers northeast of Pompeii. It was built in the 2nd century AD. The theater is not large in scale. Compared with other theaters, it can only be considered a pocket version, but the building materials used are relatively high-end. There are 14 rows of ring-shaped white marble seats. The surface is still smooth and flat. It can accommodate 800 spectators. There are some remaining pillars around the theater.
