Fort Union Trading Post National Historic Site is located in Garfield County, Montana. The site consists of the ruins of the second Fort Union, a fur trading post that was operational from 1828 to 1867. The fort was built by the American Fur Company and was the largest fur trading post in the western United States. It served as a major hub for trade between Native Americans and Americans, and played a significant role in the westward expansion of the United States. Today the site includes the remains of the original fort, as well as a Visitor Center with exhibits on the history of the fur trade.
