Shipwreck salvaging was the source of Key West’s first great boom in the early to mid-19th century, so although this slick multimedia bit of business has a certain theme-park feel to it, if you’re curious about the phenomenon, and that era in general, this is probably the single most comprehensive collection there is. The two-story re-creation of an 1850s warehouse mixes film, actors playing period roles, and artifacts from salvaged cargo items. As a bonus, you can climb the 65-foot lookout tower atop the museum for a great view over this corner of the island and out to sea.
