The Huguenot Cemetery 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.
Prior to American occupation the Spanish city of St. Augustine was predominately Catholic and the only burial ground within the city, the Tolomato cemetery, was reserved for Catholics. Recognizing a need for a formal Protestant burial ground an area just outside the city gate was chosen by the new American administration in St. Augustine. The first burials occurred in 1821 just prior to a yellow fever epidemic which claimed the lives of a large numbers of the city's inhabitants.
