Port City of Acco
Acco is only referenced once in the Bible by this name. In Judges 1:31, it is referred to as one of the places the Israelites failed to hold. In the New Testament, Acco was known as Ptolemais, and was one of the stops on Paul's final return to Jerusalem (Acts 21:7). Ptolemais was situated on the main sea and land route in ancient times. It served as the main port of the region until Caesarea was built. Herod the Great received Augustus Caesar at this site, since Caesarea had not yet been completed. Vespasian first docked at Ptolemais when he came to subdue the First Jewish Revolt. Later, the Arab inhabitants changed the name back to "Acco."
