At the Key West Shipwreck Treasure Museum, you will step back in time as you discover Key West’s unique maritime heritage and how it became the richest city in the United States. The museum combines actors, films and the actual artifacts from the 1985 rediscovery of the wrecked vessel Isaac Allerton, which sank in 1856 on the treacherous Florida Keys reef. Also, climb the 65-foot lookout tower for spectacular views of the island.
