Stockton Springs’ rich history dates back to indigenous people who lived in the area and fished in the harbor. In the mid-1800s, Stockton’s industry thrived. It included four sawmills, a tannery, six blacksmith shops, four shipyards, a shoe factory, a cheese factory, and a clothing factory. At the turn of the 20th century, Stockton Harbor was a bustling port where schooners came and went with the tides.

There were three huge wooden piers, the largest measuring 1,750 feet. Stockton housed the largest potato warehouse, with potatoes arriving from Aroostook County and stored in their custom potato box. The Bangor and Aroostook railroad transported goods to and from the massive docks. A devastating fire destroyed the piers in 1924, putting an end to the industrial era of Stockton Harbor’s history.
