Members of the Lighthouse Archaeolgoical Maritime Program utilized a life davit to extract an 18th century, 1,200 pound cannon from a shipwreck off the coast of St. Augustine, Florida 30-ft beneath the ocean. The cannon was spotted from a lighthouse and at the St. Augustine pier exposed by sunlight.
This is the second-oldest shipwreck discovered off the NE Florida coast, with the ironworks having to date post-1776. The cannon is believed to be from Colonial-period, most likely around the time of the Revolutionary War and appear to have been made by Carron Ironworks of Scotland.

The cannons are on display currently behind the Lighthouse Museum while they are in water baths during the tedious encrustration removal procedure over the next 2 years.
