The ancient city of St. Augustine, the oldest place of European settlement on the North American continent, is on the east coast of Florida at the mouth of the St. Augustine River and at the northern end of a long lagoon formed by Anastatia Island, which separates the waters of the lagoon and of the Atlantic Ocean. Our interest in the quaint spot may be concentrated in Fort Marion, a Spanish bravo which has fought the city’s battles for more than three hundred and fifty years. Probably the most picturesque of fortifications in the United States, Fort Marion annually receives thousands of visitors, many drawn from the leisured throng who have made St. Augustine the winter social capital of the American nation. [Illustration: By courtesy of the St. Augustine Historical Society MOAT AND ENTRANCE, FORT MARION, ST. AUGUSTINE, FLA.] Fort Marion is situated at the northern end of St. Augustine, where its lonely watch-tower may have a clear view of the shipping channel which leads from the city across the long bar Anastatia Island to the ocean. The fortification is a regular polygon of four equal sides and four bastions. A moat surrounds the structure, but the moat has been dry for many years. The entrance is to the south and is protected by a barbican, or, less technically, an arrow-shaped out-work. A stationary bridge leads part way across the moat and the path is then continued on into the fort by a draw-bridge. Over the entrance is an escutcheon bearing the arms of Spain with gorgeous coloring, which has been much dimmed by the hot sun of Florida. A legend now partially obliterated sets forth that “Don Ferdinand, the VI, being King of Spain and the Field Marshal Don Alonzo Fernando Hereda, being Governor and Captain General of this place, San Augustin of Florida, and its province, this fort was finished in the year 1756. The works were directed by the Captain Engineer Don Pedro de Brozas y Garay.” Passing through the entrance to the fort one finds one’s self in a dark passage, on the right and left of which are low doorways, that on the right being the nearer. Glancing through the right door-way one sees three dark chambers, the first of which was used as a bake-room and the two others of which were places of confinement for prisoners. Looking through the dark door-way a few steps forward to the left one gazes into the guard-room. Walking on one comes into the open court, 103 feet by 109 feet; immediately to the right is the foot of the inclined plane which leads to the upper walls. To the left is the well. On all sides of the court are entrances to casemates. Directly across from the entrance is the ancient chapel, which heard masses sung while the English colonies were just being started. The altar and niches still remain and over the door of this place of worship is a tablet set in the wall by French astronomers, who here once observed the transit of Venus.
