Mel Fisher Maritime Museum

For a fascinating glimpse into Key West's complicated history, pay a visit to this popular museum near the waterfront. It's best known for its collection of gold coins, rare jewels and other treasures scavenged from Spanish galleons by Mel Fisher and crew. More thought-provoking is the exhibition devoted to the slave trade, with artifacts from the wreck of the Henrietta Marie, a merchant slave ship that sank in 1700.
