A seaport is a port, harbor, or town accessible to seagoing ships. It is an artificial harbor or wharf constructed to receive sea-going vessels, such as ships and barges. Seaports are used for loading and unloading cargo and passengers from ships. They can comprise one or more wharves where ships can dock. Seaports are important for international trade and commerce, as they provide a connection between land and sea transportation. They are also important for the economy of the cities or towns where they are located, as they can create jobs and generate revenue.
