Bosra is a historical city located in southern Syria. It is an important archaeological site that was once one of the largest cities in the Roman Empire. The city's well-preserved ruins include the impressive Roman theater, one of the largest in the world, with a seating capacity of 15,000 spectators. The theater is still used today for cultural events and performances.

Bosra is also home to the ancient Roman city gate, the Nabatean-style al-Omari mosque, and the remains of the ancient Roman aqueduct. The city's citadel, which dates back to the 9th century, sits atop a hill and offers a panoramic view of the surrounding area.

In 1980, Bosra was designated as a UNESCO World Heritage Site due to its unique combination of historical, cultural, and architectural significance. It is considered to be one of the best-preserved examples of a Roman city in the Middle East and is a popular tourist destination for those interested in ancient history and archaeology.
