Granite Quarries

The Cathedral of St. John the Divine in New York City, the John F. Kennedy Memorial at Arlington National Cemetery, the Statue of Liberty, the approaches to the Brooklyn Bridge, President Ulysses S. Grant’s tomb, and Sing Sing Prison all have one thing in common: granite from Maine.
Formed millions of years ago by cooling magma, granite is found all over the state, but is particularly exposed on the coast, where glaciers scraped away the surface in the last ice age. That so much exposed granite is along Maine’s coast turned out to be fortuitous for commercial purposes as the heavy stones could easily be conveyed by water to major transportation hubs, from where Maine’s granite then made its way to construction projects all along the East Coast.
Because of the access to shipping, much of the state’s granite quarrying business was centered along the coast. For a time between the mid-1800s and the early twentieth century, granite turned communities like Stonington, Vinalhaven, and Hallowell into boom towns. At the industry’s peak in 1901, more than 150 granite quarries were in operation in Maine.
Crucial to the industry were immigrants, some of whom were skilled stoneworkers who worked quarrying marble in Italy. The work they did in Maine’s granite quarries was strenuous and dangerous. The possibility of injury or death from getting crushed, dynamite blasts, cave-ins, and debilitating lung diseases from inhaling stone dust was a daily reality. Those working conditions, as well as low pay, resulted in the state’s granite workers forming the first granite industry union in the United States in 1877.
Demand for granite as a building material dropped in the first decades of the twentieth century as steel and concrete replaced stone, but Maine granite is still quarried today. While the state’s granite mainly is used for curbing, kitchen countertops, and landscaping, it is still occasionally incorporated into major projects, such as the recently completed restoration of the terreplein deck that forms the pedestal base of the Statue of Liberty.
