2013 Map of Unionville

About this map

The W Br Brandywine Cr and E Br Brandywine Cr converge within this corner of Chester County, shaping a landscape defined by historic crossroads settlements and colonial-era mill sites. In the north, the Penn Central Railroad corridor through Thorndale and Gallagherville marks the industrial expansion of the Brandywine Valley, while the southern reaches near Unionville and Marlboro retain a more rural, agricultural character. The map reveals the intricate network of family-named landmarks and small villages like Lenape and Wawaset that grew around the water power of the creeks. Notable institutional features include the Philadelphia YMCA Camp and the site of Saverys Mill, providing a detailed look at the 21st-century transition between preserved open space and residential growth in the Brandywine watershed.
