The aim was exploring the ancient history of the area since the valley was particularly important during the Late Classical and Hellenistic periods as a route connecting the northern and southern parts of Greece.
[1] The project was a collaboration between the Fthiotis and Evritania Ephorate of Antiquities, under the direction of Maria Foteini Papakonstantionou and Swedish archaeologist Anton Bonnier.
Bonnier directed the work carried out by the Swedish archaeological team and focused on two Hellenistic fortified hill-sites, Profitis Elias and Kastrorachi, as well as their surrounding area.
[2] The Spercheios valley of historical times is mentioned only sporadically in the ancient textual evidence, by Herodotos and Thucydides, leaving archaeological material as the main sources of information.
The material found gives the impression of a primarily domestic habitation and included fragments of a Doric column or pilaster and remains of several Olynthian mills as well as various kinds of lamps and two Hellenistic coins.
