Pre-Roman ancient ruins are just a day trip from Kusadasi in the ruined city of Sardis, the capital of the kingdom of Lydia from the 7th to 6th centuries BC.
For a time Sardis (Sart, today) was renowned throughout classical antiquity as the richest city on the planet, known for its legendary supply of gold washed down from the Tumulus Mountains.
The term ‘rich as Croesus’ refers to that gold and the last Lydian ruler, King Croesus, who is thought to have invented gold coins.
