Fort St. Marks is situated on a point of land formed by the junction of the Apalachicola and another river about the same size, and insulated by a deep wet ditch, joining the rivers. The fort is built of hewn stone; the walls are nearly 20 feet high, and defended by twenty pieces of ordnance. It was formerly a place of considerable importance and the residence of some of the Spanish Governors; but has been on the decline ever since the Floridas were ceded to Great Britain by the peace of 1763,-On account of the shoals, and numerous oyster banks in the Bay and River, it is not considered as a good sea-port, but is advantageously situated for the Indian trade.
