Historical Materials: Maritime & Other Industries & Facilities

The harvesting of granite from quarries dug deep into the earth was an important industry on Cape Ann from the 1830s through the early 20th century. Second only to fishing in economic output, for 100 years the granite business played a pivotal role in the local economy providing jobs for many, turning profits for some and generating tons and tons of cut granite that was used here on Cape Ann and shipped to ports all along the Atlantic seaboard.

Granite quarrying started slowly in this area in the late eighteenth century with small operations peppered across the rocky terrain. Construction of a fort at Castle Island in Boston Harbor in 1798 followed by a jail in nearby Salem in 1813, jump-started the granite industry here on Cape Ann. During the 1830s and 1840s, the trade grew steadily. By the 1850s, the stone business was firmly established and Cape Ann granite was known throughout the region. So extensive and so awe-inspiring were operations during the second half of the nineteenth century some observers feared that the business might actually run out of stone.

While granite was taken from the earth in all different sizes and shapes, Cape Ann specialized in the conversion of that granite into paving blocks which were used to finish roads and streets. Millions of paving stones were shipped out of Cape Ann annually, destined for construction projects in New York, Philadelphia and all along the Atlantic seaboard. While paving blocks were basically uniform in size, there were subtle differences leading some to be referred to as Philadelphia blocks while others were identified as Boston blocks or Washington blocks.
