Located on Florida's Treasure Coast, Stuart is the largest of four incorporated municipalities in Martin County. Several Spanish galleons were shipwrecked in this area of Florida's Treasure Coast in the 18th century. In 1832, pirate Pedro Gilbert often used a sandbar off the coast as a lure to unsuspecting prey. He chased and captured the Mexican, a US merchant ship. He attempted to burn the ship and kill the crew, but they survived and reported the incident. Gilbert and his crew were captured and executed. The bar from which is lured his prey is called "Gilbert's Bar" on nautical charts.
