Androscoggin County

A compact inland county shaped by the Androscoggin River, the neighboring cities of Lewiston and Auburn, mill-era industry, and a connected group of rural communities.

County overview

River, cities, and working communities

Androscoggin County contains the Lewiston–Auburn urban center and a surrounding landscape of towns, farms, forests, waterways, and former mill communities. It is one of Maine’s counties and was established in 1854 from towns previously belonging to neighboring counties.

Lewiston and Auburn grew on opposite banks of the Androscoggin River. Waterpower supported industrial expansion, while successive communities—including French Canadian workers and, much later, immigrants and refugees from several regions—added new chapters to the area’s social and cultural life.

The county’s boundaries continued to change after its creation. Danville became part of Auburn in 1867, while Mechanic Falls was formed from portions of Minot and Poland in 1893.

Formation

The Maine Legislature created Androscoggin County in 1854 by combining communities from Cumberland, Kennebec, Lincoln, and Oxford counties. An early county map is available through the Map Cabinet.

County government

The City of Auburn is the county seat and the center of county government. Across the river, Lewiston is the larger city and is home to Bates College and collections associated with Edmund S. Muskie.

The Androscoggin River

Rising in New Hampshire and flowing into Maine, the Androscoggin divides Lewiston from Auburn. Its falls and current supplied power for mills and helped determine the location and growth of both cities.

The river also carries a complicated industrial legacy. Dams, pollution, and inadequate fish passage sharply changed its ecology, including historically important salmon habitat. Restoration and water-quality work form part of its more recent story.

County courthouse and jail

The Androscoggin County Courthouse and Jail is a Renaissance Revival civic landmark associated with the county’s formation and the prolonged debate over the location of its shire town.

Once Auburn was selected in 1854, courthouse planning moved forward quickly. Completed in 1857, the building became a visible symbol of the newly organized county and the resolution of the county-seat dispute.
