The city we know as Byblos in the Western world is a Mediterranean city in the Mount Lebanon Governorate of present-day Lebanon, called Jbeil (جبيل Ǧubayl) in Arabic. It is believed to have been founded around 5000 BC, and according to fragments attributed to the semi-legendary pre-Trojan war Phoenician historian Sanchuniathon, it was the first city ever built, and even today is believed by many to be the oldest continuously-inhabited city in the world.
It is mentioned in the Bible in 1 Kings 5:32, referring to the nationality of the builders of Solomon's Temple.
So, it's old.
