East of here, on the Chattahoochee River, was the "fort among the Apalachicolas," most northern of the Spanish settlement in eastern North America. A palisaded "strong house" built by Captain Enrique Primo de Rivera to check activities of English traders, it was destroyed when the garrison was called to St. Augustine because of a threatened attack by the French. Undisturbed except by natural forces, the ruins remainedvisible but unrecognized for 250 years. Research by Mark E. Fretwell and a search of the ground by Brother Finbar Ray led to their identification and designation as a National Historic Landmark in 1966.
