With a history dating back to 6000 BC, Adana is one of the oldest settlements in Anatolia and is the fourth largest city in Turkey. Interest in the city is not only due to its collection of historical sites, but it is also renowned as a thriving, modern region. Its population boom (now 1.5 million) can be attributed to its fertile plains, rivers and highlands, which have created a major textile industry, and the city is also an importing trading centre for gold.
