Fort San Carlos
(1764 - 1768, 1778 - 1794, 1799 - 1819), Baton Rouge
The French may have built a fort here as early as 1721 to subdue the local Indians, but it was the British who took control of the newly created West Florida Province in 1763 and built Fort New Richmond (1764 - 1768). The earthwork fort was rebuilt in August 1778 (known as Fort Richmond by this time) with an 18-foot wide and nine-foot deep moat, armed with 13 guns. It was located near present-day Boyd Ave. (Spanish Town Road) and Lafayette Street. American Patriot forces briefly took the new fort in 1778, but were soon captured by the British. The Spanish took the town and fort in September 1779, rebuilt it, and by 1781 controlled all of West Florida. The fort was rebuilt again in 1799 as a six-pointed star-shaped 16-gun fort, slightly east of the 1778 British earthwork fort (now a parking lot across River Road). The local British and American settlers rebelled against the Spanish authorities in September 1810 and proclaimed the "West Florida Republic" (or "Baton Rouge Republic"). The U.S. Army took possession in December 1810, naming it Post at Baton Rouge. Demolished when the Pentagon Barracks was built nearby. There are some concrete/brick walls and sidewalks around A.Z. Young Park and the Capitol Park Event Center (702 River Road) that partially outline the perimeter of the last Spanish fort.
