In which of the following countries can this facade of a Greco-Roman amphitheater be found?

The Ancient Greek city of Hierapolis, also known today as Pamukkale, (Cotton Castle in Turkish) is located in southwestern Turkey. The nearby area is famous for its thermal spring waters. “Cotton Castle” is a reference to the snow-white limestone formations in the area. The ancient city was built right on top of the travertine formations.

The hot springs have been used as a spa since the 2nd century BCE. They were enjoyed by both ancient Greeks and Romans, as evidenced by the facade of an ancient Greco-Roman theater which was once home to baths, a gymnasium, an agora (open meeting space), and a temple.

The theatre is thought to have been built during the reign of Hadrian, after the earthquake of 60 CE. In 133 BC, when Attalus III, king of the Greek state of Pergamon died, he ceded his kingdom, including Hierapolis, to Rome.

The city continued to flourish during the 2nd and 3rd centuries CE. It was at this time, during the reign of Septimius Severus at the beginning of the 3rd century, that the theater underwent major renovations, the auditorium was rebuilt, and limestone seats were replaced with marble. Despite the high quality of workmanship and materials employed, an earthquake in Hierapolis during the 7th century caused the collapse of the majority of the building, except the facade, and ultimately led to the abandonment of the city by the 14th century.

The area has been excavated steadily since the 19th century, and is now an official UNESCO World Heritage Site.
