In 1824, the completion of the Schuylkill Canal gave birth to Spring City, and the opening of the Philadelphia and Reading Railroad in Royersford soon followed. Over the years, the "twin boroughs" grew simultaneously, sharing the community and industrial developments that their respective transportation hubs fostered. Spring City and Royersford, through more than two hundred vintage postcards, shares the history of these sister towns: the stove factories, glassworks, and knitting mills that were found on both sides of the river; the floods, fires, and train wrecks that the towns endured; and the bridges, schools, and celebrations that help unite the two communities.
