For centuries, the exact location of Tristán de Luna y Arellano’s 1559 settlement in Pensacola — the first multi-year European settlement in the United States — has been a mystery.
Not anymore.
Archaeologists from the University of West Florida announced on Thursday the discovery of one of the most significant historical sites in the nation: the archaeological site of the de Luna settlement, hidden just beneath the surface in the city’s East Pensacola Heights neighborhood.
“Our archaeological team has discovered and can support the statement that the land settlement site of Tristan de Luna has been located within the city limits of Pensacola, Florida,” said Dr. Judy Bense, the university’s current president and founder of its archaeology program. “And we are telling the world today.”
