Fort Andross, also known as Fort George and Cabot Mill, was initially established as a trading post and later converted into a historic garrison by the colonial British Empire as a defensive measure against the Wabanaki Native Americans who were allied with France during King William's War (1688–1697). It was situated next to Brunswick Falls, on the Androscoggin River in Brunswick, Maine. During the war, the fortification was destroyed, rebuilt, and renamed Fort George in 1715. Once the Native American wars came to an end, the fort was abandoned.

Brunswick Falls, also known as Pejepscot Falls, lie on a rocky section of the Androscoggin River, bordering the towns of Brunswick and Topsham, Maine in the US. First occupied by Paleoindians and the Wabanaki Native Americans, the falls were a plentiful resource for food and trade. Throughout colonial history, the Industrial Revolution, and into the 21st century, the falls have been a vital part of Brunswick and Topsham's economy, harnessing its power for energy development.
