Mastaura

Archaeologists have found a sewer system believed to be 1,800 years old during excavations in the ancient city of Mastaura in the western province of Aydın's Nazilli district.

Experts have been working on the site, located inside a narrow valley and some 3 kilometers north of Nazilli, for the past two years.

An ancient structure similar to the world-famous Colosseum amphitheater in Rome has been discovered during ongoing archaeological excavations in the ancient city of Mastaura in the Aegean province of Aydın's Nazilli district.

It is reported that the structure, which was cleaned and became visible, is unique in Turkey due to the fact that it is completely round.
