THE STORY BEHIND THE PHOTOGRAPHS

People, places, and change.

A nineteenth-century building material

During the second half of the nineteenth century, Portland’s quarries supplied the reddish sandstone associated with urban brownstone houses. The National Park Service identifies these workings as the principal source of a material used for both grand residences and middle-class homes. A local extractive industry thus helped shape streets far beyond Connecticut. [2]

Workers and vessels

At the industry’s late-nineteenth-century height, the Town of Portland records roughly 1,500 quarry workers and at least 25 vessels carrying stone to market. The river mattered as much as the rock: it connected cutting and loading operations with buyers. The 1911 postcard in this collection supplies a period view of the quarry landscape. [1]

Stone in Portland and scientific study

The quarries also supplied local schools, churches and public buildings, including Portland’s 1894 town hall. Their significance extends beyond architecture. Geologist Paul Dimitri Krynine used evidence from Portland in a major study showing that red sedimentary beds could form in humid tropical environments, as well as arid ones. [1] [2]
