Plovdiv is the second-largest city in Bulgaria after Sofia, with a city population of 346,893 as of 2018 and 675,000 in the greater metropolitan area. Plovdiv is the cultural capital of Bulgaria. It is an important economic, transport, cultural, and educational center. There is evidence of habitation in Plovdiv dating back to the 6th millennium BCE when the first Neolithic settlements were established.
