This harbor was probably used for fishing and not for trade by the Phoenicians. The bottom of the current harbor is not deep enough to be able to receive the large ships used for the Phoenicians’ active maritime trade. Archaeologists are still searching for the location of the ancient Phoenician harbor.
The Crusaders built defensive towers on either side of the mouth of the port, and a chain could be raised between the two towers to prevent boats from entering. The northern tower was restored during the Mamluke and Ottoman eras and is still in fairly good condition.
