The Barges dive site is located on the north side of Grande Island. It is not what you would typically consider a wreck site, it does have a personality of its own. The true origins of the “barges” are unknown, however, I do have my own theory. I am convinced of it but lack documentary proof. I will present my theory later. Grande Island’s military importance dates back to the original Spanish fort. It became Fort Wint under the U.S. Navy until captured by the Japanese in WWII. After recaptured by US near the end of the war, it never regained its military significance. It was later used as a R&R center and at the end of the Vietnam war as a refugee camp.
