Susa no longer exists today, but Shush is a small town that is more or less on the site of the ancient city. We can therefore see a certain continuity. Susa dates from 8000 BC was the capital of the Elamite Empire before it was captured by the Assyrians. It was then taken by the Achaemenids Empire under Cyrus the Greek. It is the city where the play of the Persians of Aeschylus takes place, an Athenian tragedy that is the oldest play in the history of the theatre. The modern city, Shushan, has a population of around 65,000 people and is also mentioned in the biblical books of Esther.

The second-largest city in Bulgaria, Plovdiv was originally a fortified Thracian city, before becoming a large Roman city. It later fell into the hands of the Byzantines and Ottomans, before integrating Bulgaria. The city is an important cultural centre and is home to many ancient remains, including an amphitheatre and a Roman aqueduct, as well as Ottoman baths. Throughout its history, it was dominated by Byzantines and Ottomans until, finally, the Bulgarians conquered it in the year 815. The name Plovdiv first appears in the 15th century. e
