Ancient Lilaia, one of the nine Phocian cities mentioned by Homer as having joined in the Trojan war, and Polydrosos, were in ancient times two cities that flourished greatly due to their favourable positioning on the crossroads of the two main roads connecting Thessaly to southern Greece. They were inhabited since the 3rd millennia B.C. and visitors can still make out in the region the fortification, a font construction, and the ruins of a sanctuary, while there are bountiful springs with clear water that seem to still worship the river god Cephissus, as they did then.
