The Huguenot Cemetery (also known as the St. Augustine Public Burying Ground) in St. Augustine, Florida located across from the historic City Gate was a Protestant burial ground between the years 1821 and 1884. The Spanish colonial city of St. Augustine, along with the entire Florida Territory became de facto American possessions after the 1819 signing of the Adams-Onis Treaty. The actual physical occupation of the city and Florida territory occurred in 1821.
