Learn About the Park

First State National Historical Park (NHP) is made up of seven sites spread throughout the entire state of Delaware. While visiting the park you will learn about the triumphs and struggles of the first settlers in the Delaware Bay and how Delaware played a role in establishing our nation, becoming the first state. First State NHP does not currently have one central visitor center, but each of the seven sites has some type of welcome center where you can receive information about and take a tour. To learn more about the seven sites visit the "Basic Information" page.
