A harbour is a sheltered area along a coastline where ships and boats can dock safely. It provides protection from rough waters and harsh weather, allowing vessels to load and unload cargo or passengers. Harbours can be natural, formed by the geography of the land, or artificial, created by human engineering. Harbours often include facilities such as piers, docks, and warehouses. They play a crucial role in trade and transportation, connecting different regions and countries. Many cities, like New York and Sydney, have busy harbours that serve as vital economic hubs for shipping and tourism.
