Side Harbor, Temple of Apollo
Constructed sometime during the Hellenistic period, the ancient harbor of Side used to be located on the southeast part of the peninsula, next to the temples of Apollo and Athena. It originally had a coastline which went all the way to the harbor baths. Silting from the river required constant dredging. This was such a constant and difficult task that the dredging of the harbor of side was used, in ancient times, as an expression for any task which was never-ending, difficult, and very costly. The harbor was finally abandoned in the 5th century, and the silt eventually caused the shoreline to receded to its present location, some 250 to 300 meters from the harbor baths.
