Present-day Sellia was founded between the 9th and 10th centuries AD by refugees from the ancient coastal town of Trischene, who, to escape Saracens' raids, took refuge on the Sellion mountain. In the new location, whose position ensured greater protection against enemy attacks, they gave birth to a new center named Asilia, from which the name Sellia was derived.
