Fort San Francisco de Pupo (Spanish: Fuerte San Francisco de Pupo) was an 18th-century Spanish fort on the west bank of the St. Johns River in Florida, about eighteen miles from St. Augustine (San AgustÃn), the capital of Spanish Florida (La Florida). Lying on the old trail to the Spanish province of Apalachee in western Florida, Fort Pupo and its sister outpost, Fort Picolata on the opposite shore of the river, controlled all traffic on the ferry crossing. The remains of Fort Pupo are situated about three miles south of Green Cove Springs in Clay County, near the end of Bayard Point opposite Picolata. The surrounding area is a hammock of southern live oak, southern magnolia, pignut hickory and other typical trees native to the region. Read more on Wikipedia
