St. Francis Barracks is a historic structure constructed of coquina stone located on Marine Street in St. Augustine, Florida, named in honor of St. Francis of Assisi. The barracks were constructed between 1724 and 1755 by monks of the Order of St. Francis, to replace a series of wooden buildings which had been destroyed by the ravages of the tropical climate in La Florida and by fire, both accidental fires and occasional intentional ones, such as when the city was razed by the English in 1702.
