McAllister's Mill Underground Railroad Station

Near Gettysburg, a grist mill on Rock Creek served a far more urgent purpose than grinding grain. James McAllister and his family sheltered hundreds of freedom seekers at their mill, making it a key station on one of the earliest Underground Railroad networks in Pennsylvania. People escaping slavery rested here before continuing north toward freedom.

On the Fourth of July, eighteen thirty-six, the mill became the site of an important gathering of abolitionists that led directly to the founding of the Adams County Anti-Slavery Society, an early and influential organization in the region's antislavery movement. The mill now stands in ruin, a quiet testament to the courage of those who passed through and those who risked everything to help them.
