Ancient Lilaia, located on the northern flank of Parnassos, was close to the main sources of the Kephisos, with which it also had a strong connection. The Kephisos had a sanctuary near the city itself, and the priest of the Kephisos was the eponymous magistrate of the city. The city was destroyed in the third Holy War, and rebuilt afterwards. No traces are found of the theater, the agora and the bathhouse. The city walls of Lilaia are clearly visible on the slopes of the Parnassos, with a particularly impressive acropolis.
The main sources (Kefalária) of the Kephisos are at a distance of about 900 meters from Lilaia, where in ancient times the river god was also worshiped, and some religious buildings have been replaced in the early Byzantine period by two churches. Scarce remains of the first church, dedicated to Christoforos, have been preserved directly above the wells (including the foundations of an apse), while a second church, dedicated to Saint Eleousa Souvala, was a hundred meters away. Especially in this church much antique material has been reused (partly with Christian symbols), so there is hardly any doubt that there was a temple nearby dedicated to the river god. As Pausanias mentions, part of the rituals consisted of throwing sweets into the well (10.8.10). A second source was located 4-5 km. northeast of the town; there too the deity will be worshiped
