A harbor or harbour (see spelling differences), also called a haven, is a body of water where ships, boats, and barges seek shelter from stormy weather, or are stored for future use. The term harbor, referring primarily to a sheltered body of water, is often used interchangeably with port, which is a man-made facility built for loading and unloading vessels and dropping off and picking up passengers. Ports usually include one or more harbors. Alexandria Port is an example of a port with two harbors. (source)
