The Roman Theatre of Orange, located in the town of Orange in southeastern France, is one of the best-preserved Roman theaters in the world. It was built during the reign of Emperor Augustus in the 1st century AD and was designed to seat up to 10,000 spectators.

The theater is built into a hillside, and its stage wall is nearly 103 meters wide and over 37 meters high, making it one of the largest surviving Roman theaters. The stage was originally decorated with elaborate statues and carvings, many of which can still be seen today. The theater was used for various performances, including plays, music, and gladiatorial contests, for over three centuries before it fell into disuse.

In the Middle Ages, the theater was used as a fortress, and many of the original decorations were destroyed. It was not until the 19th century that efforts were made to restore the theater to its original grandeur. Today, the theater is a UNESCO World Heritage Site and is still used for performances during the summer months.
