Learn About the Park

First State National Historical Park is made up of seven sites spread throughout the entire state of Delaware. The park focuses on the story of first settlement through the ratification of the United State Constitution. First State NHP does not currently have one central visitor center, but each of the seven locations does have some type of welcome center where you can receive information about the site and available tours. To learn more about the seven sites visit the "Basic Information" page.
