A portion of Via Egnatia, an ancient Roman road, passes through Spilia. An archaeological site of the ancient Macedonian tomb of Eordaia (Greek: Μακεδονικός τάφος Σπηλιάς) is located in Spilia along this road. The architectural form shows the tomb and monument to be in the same category as tombs of Philip II, Vergina, and Leukadia.
