Itilo takes its name after the hero of the Greek mythology Itilos, who was the son of Amfiaktanas. It seems that Itilo has actually been inhabited even since antiquity.
More specifically, during the Homeric years, Itilo was part of Menelaos’ kingdom. The historian Pafsanias mentions that it was one of the most important cities in the region.
Nowadays, remnants of ancient monuments and inscriptions can be found around the beach, where the Temple of Serapis is located.
