Passing up the inclined plane to which allusion has already been made one finds one’s self on the ramparts of the fort. A charming view is to be obtained on all sides, but particularly looking out to sea. At each angle of the fort was a sentry-box and that at the northeast corner was also a watch-tower. This tower, probably the most familiar remembrance of old Fort Marion, is twenty-five feet high. The distance from watch-tower to sentry-box (or from corner to corner) of the old fort is 317 feet. The material of which the fort is constructed is the familiar sea-shell concretion used so largely in Florida and known as “coquina.” It was quarried on Anastatia Island, across Matanzas Inlet from the city, and was ferried over to the fort site in large barges. The substance is softer when first dug than when it has been exposed to the air and light for a season, sharing this property with concrete, to which it is analogous in other ways, so the walls of the fort are more solid to-day than when they were built. The history of Fort Marion takes one back to early bickering between Spanish and French on the North American continent. In 1562 Jean Ribaut, a sturdy French mariner, sailed into the waters of Florida, explored the waters of the St. John’s River (at the mouth of which busy Jacksonville now stands) and planted a colony and a fort on the St. John’s with the name of Fort Caroline. The river he called the River of May, in remembrance of the month in which he first set eyes upon it. In 1564, Laudonierre, a second Frenchman, came with supplies and reinforcements for Fort Caroline, but paused on his passage to investigate an inlet farther south than the mouth of the St. John’s River. This inlet he called the River of Dolphins, from the abundance of such creatures at play in the waters here and on the shores of the inlet, which later generations were to know as St. Augustine harbor; he descried an Indian village known as Seloy. The jealous King of Spain heard of the French settlement in Florida and was displeased. He sent an expedition under Juan Menendez de Aviles to colonize the country with Spaniards and to exterminate the French, who added to the misfortune of not being Spaniards the mistake of not being Catholics. Menendez sailed into Florida waters in September, 1565, reconnoitred the French colony on the St. John’s River and then sailed south several days, landing at the Indian village of Seloy. Here he decided to establish the capital of his domain. The large barn-like dwelling of the Indian chief was made into a fort. This was the original of Fort Marion of to-day. Then on September 8, 1565, Menendez took final possession of the territory, and named his fort San Juan de Pinos.
