New Philadelphia, Illinois, a once-thriving community founded by freed African American Frank McWorter in 1836, has gained new life as a National Historic Site. The town, which welcomed residents of all races decades before the Emancipation Proclamation, reached its peak with about 100 residents but dwindled after a railroad bypass in 1869. Today, visitors can explore the site through augmented reality experiences and educational signage.

McWorter's remarkable journey from enslavement to landowner saw him purchase freedom for himself and 15 family members, spending what would be equivalent to over $500,000 today. The community served as an Underground Railroad stop, with McWorter harboring escaped slaves and his sons helping others reach Canada. Archaeological evidence and oral histories collected by multiple state universities and the Illinois State Museum supported its designation as both a National Historic Landmark and entry on the National Register of Historic Places.

The site's recognition came after more than a decade of research and advocacy. While the physical remains are limited to historic cabins and structures not open to the public, the National Park Service has developed innovative ways to bring the town's story to life. Located near Macomb, visitors can access the site while exploring Western Illinois University's hometown, with budget-friendly lodging options available in the area.
