The U.S. Army Corps of Engineers said Thursday the cannon, dating to the early 18th century, was found in August in one of the port’s ship turning basins by the Great Lakes Dredge and Dock Co. It was turned over in October to the Florida Bureau of Archaeological Research in Tallahassee.

Officials say the cannon will be studied and restored in the State Department’s conservation lab and then put on public display. Secretary of State Ken Detzner says the cannon will increase knowledge about Florida’s maritime history.
