Is Fort Pitt still an active Fort?
Fort Pitt (Pennsylvania)
Fort Pitt was a fort built by British forces between 1759 and 1761 during the French and Indian War at the confluence of the Monongahela and Allegheny rivers, where the Ohio River is formed in western Pennsylvania (modern day Pittsburgh). It was near (but not directly on) the site of Fort Duquesne, a French colonial fort built in 1754 as tensions increased between Great Britain and France in both Europe and North America. The French destroyed the fort in 1758 when they retreated under British attack.
Apple River Fort
The Apple River Fort played a role in the 1832 Black Hawk War, being one of the few forts that was attacked during the conflict, and the only fort attacked by a band led by Black Hawk himself. The site of the original fort still holds the potential to yield significant sub-surface archaeological artifacts and data. For its military and archaeological significance, the Apple River Fort Site was added to the U.S. National Register of Historic Places on November 7, 1997. On January 1, 2001 the state of Illinois took over operation of the reconstructed Apple River Fort and its interpretive center. The state now operates the area as the Apple River Fort State Historic Site. Illinois' purchase was funded, in part, through a US$160,000 Illinois FIRST grant.
