A "Port City" is a coastal city or town that has a harbor where ships can dock to load and unload cargo. These cities often serve as important hubs for trade and transportation, connecting different regions and countries. The presence of a port can significantly boost the local economy by creating jobs and attracting businesses related to shipping, logistics, and tourism. Many port cities, such as Los Angeles, Shanghai, and Hamburg, have developed unique cultures and infrastructures due to their maritime activities. They often feature waterfront attractions, such as marinas, fishing docks, and beaches, making them popular destinations for both residents and tourists.
