      <MissionDesc>The Core Purpose or Mission of the Independence Seaport Museum is to discover Philadelphia's river of history and world of connections. Serving a wide and diverse audience and holding its collections in trust for the community, the Museum tells the stories of the people, historical events and environmental changes of the Delaware River and its tributaries. It looks to a broad regional definition of the River to include both Philadelphia and Camden as well as portions of the southern coast of New Jersey and the Schuylkill river drainage.</MissionDesc>
