Built in Germantown from 1765–68, the Johnson House functioned as a residence for five generations of the Johnson Family until the early 20th century. The Johnsons were active abolitionists and the house is documented as a site for Underground Railroad activities. Now a National Historic Landmark, the Johnson House interprets the story of the struggle for freedom. A 2013 Center grant to support historic preservation work will provide increased public access and structural stability for this significant site.
