A brochure describing the history of the Castillo de San Marcos, the oldest masonry fort in the continental United States. Located at 11 South Castillo Drive in St. Augustine, Florida, the fort was designed by Ignacio Daza and constructed from 1672 to 1695, during the first Spanish period in Florida history. When the British gained control of the Florida Territory in 1763, St. Augustine became the capital of East Florida and the Castillo de San Marcos was renamed Fort St. Mark. The name was changed back in 1783 when Spain regained control of Florida. In 1821, Spain ceded Florida to the United States and the U.S. Army renamed the site Fort Marion. The fort was declared a national monument in 1924 and was deactivated as a military site in 1933. The original name of Castillo de San Marcos was restored in 1942.
