Lower Saucon Township provides a unique glimpse of the region's many diverse villages and the German immigrant population. Towns including Wassergass, Shimersville, Polk Valley, Redington, and Bingen were settled largely because of the area's fertile soil, abundant water, and many iron and limestone deposits, which contributed to surrounding communities such as Bethlehem and Hellertown both socially and economically. These rare family photographs depict a blend of lives that influenced the area before and after the industrial revolution.
