History: Plovdiv's history spans 6,000 years, with traces of a Neolithic settlement dating to roughly 4000 BC, ranking it among the world's oldest cities. Plovdiv was known in the West for most of its recorded history by the Greek name Philippoupolis (Φιλιππούπολις), which was introduced in 340 BC. The city was originally a Thracian settlement, later becoming invaded by Persians, Macedonians, Celts, Romans, Goths, Huns, Bulgarians, Crusaders, Russians and Ottomans.
Plovdiv is situated in south-central Bulgaria on the two banks of the Maritsa River. The city has historically developed on seven syenite hills, some of which are 250 m high. Because of these hills, Plovdiv is often referred to in Bulgaria as "The City of the Seven Hills".
