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 friars 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.The barracks were turned into a military structure by the British in 1763, after Florida became a British possession at the conclusion of the French and Indian War. At that time, the Franciscan friars vacated St. Augustine, along with a majority of the other Spanish residents. The name St. Francis Barracks also came to be applied to the larger military reservation which developed around the barracks on the shore of the Matanzas River. There are several additional historic structures, to include senior military officer housing and The King's Bakery, the latter being the only extant structure in St. Augustine constructed entirely within the twenty-year period of the British occupation. Today the St. Francis Barracks is a U.S. military installation that is also known as the Florida State Arsenal and serves as the headquarters for the Florida National Guard and its two subordinate organizations, the Florida Army National Guard and the Florida Air National Guard. A portion of the military reservation is also the site of the St. Augustine National Cemetery.

The King's Bakery is a coquina stone structure in St. Augustine, Florida, built during the British colonial period in the state (1763–1783). The building, located on Marine Street, with the rear facing Matanzas Bay, was constructed to supply bread to the British troops quartered across the street at the St. Francis Barracks, a building which formerly housed Franciscan friars, during the First Spanish Period (1565–1763). The monastery was used by the British as military barracks.The bakery, believed to be the only structure remaining in St. Augustine built entirely during the British period, has been used since then as a storeroom for flour, a military hospital, and offices. The old bakery building is part of the St. Francis Barracks military compound, which since 1907 has served as the headquarters of the Florida National Guard. In 1934 it was converted for use as a garage.

Since 1939, the property has been privately owned and managed by The National Society of The Colonial Dames of America in The State of Florida (NSCDA-FL).

Lincolnville Historic District (formerly known as Little Africa) is a neighborhood in St. Augustine, Florida established by freedmen following the American Civil War and located on the southwest peninsula of the "nation's oldest city." It was designated as an historic district in 1991 and listed on the National Register of Historic Places. Originally recorded with 548 contributing buildings, the district is bounded by Cedar, Riberia, Cerro and Washington streets and DeSoto Place. In the late 20th century, numerous African Americans moved from this district to newer housing in suburbs, following the postwar pattern of settlement. In the 1990s, the city of St. Augustine engaged in extensive demolitions in Lincolnville. The number of surviving historic buildings was markedly reduced. Since the turn of the 21st century, the city has sought more demolitions to enable redevelopment of the area.
