Castillo de San Marcos National Monument in St. Augustine, #Florida. Construction on the fort began in October 1672 and was finished in August 1695 by the Spanish, who had founded St. Augustine. The fort's walls are constructed from coquina, a sedimentary rock that is composed of fragments of the shells of molluscs, trilobites, brachiopods, or other invertebrates. The coquina was mined locally in quarries. Throughout the early 1700s, the fort resisted attacks from the British, Georgian, and South Carolina forces. In 1763, the Peace of Paris gave Florida to Great Britain and the Castillo was known as Fort St. Mark. That lasted for 20 years, until Peace of Paris recognized independence of the United States and returned Florida to Spain. Florida remained in Spanish hands until 1821 when Spain ceded Florida to the United States. At this point the Castillo was renamed Fort Marion.The fort was proclaimed a national monument on October 15, 1924 by President Calvin Coolidge and in 1935 administration of the fort became the responsibility of the @nationalparkservice. #fl #flhistory #SpreadTheHistory #historygirl #nps #nps101 #goparks #nationalpark #nationalparks #nationalparkservice #goparks #americanhistory #nationalparkgeek #travelblog #travelblogger #explore #blog #blogger #exploreflorida #architecture #archi_ologie #FindYourPark #optoutside #staugustine #staugustinefl #castillodesanmarcos #monumentsforall #nationalmonument #fort (at Castillo de San Marcos National Monument) https://www.instagram.com/p/BqoHYOmlSsI/?utm_source=ig_tumblr_share&igshid=bhm7opcl0xjw
