Freeport Tortuga was a free port project by Dupont Caribbean Inc. of Texas, which began construction in 1971 based upon a 99-year contract with the government of Haiti. The location of the freeport was the old buccaneer stronghold of Tortuga island located some 10 miles off the north coast of the main Haitian island of Hispaniola, which is also shared by the Dominican Republic. Freeport Tortuga ended with its expropriation by the Haitian government in 1974.
