The Cushnoc Archeological Site, also known as Cushnoc (ME 021.02) or Koussinoc or Coussinoc, is an archaeological site in Augusta, Maine that was the location of a 17th-century trading post operated by English colonists from Plymouth Colony in present-day Massachusetts. The trading post was built in 1628 and lies on the Kennebec River. It is adjacent to Fort Western, an 18th-century stockade fort around which the city of Augusta grew.[4] The site is significant as it provides a window into trading, living, and construction practices in the early period of colonial settlement in New England. It was declared a National Historic Landmark in 1993.[2]
