Harbor sites, also known as ports, are locations where ships can dock and unload cargo. They are typically located near bodies of water, such as oceans, seas, or rivers, and provide a safe haven for vessels to rest and refuel. Ports are often used for commercial purposes, such as trading goods and services, but they can also be used for recreational activities, such as fishing and sightseeing. Ports are essential for international trade and commerce, as they provide a gateway for goods to be transported from one place to another.
