Divers Discover 19th-Century Underwater Hospital and Cemetery in Florida Keys

Archaeologists have discovered the remains of a 19th-century quarantine hospital and graveyard on an above-sea island in the Florida Keys. The hospital was used to treat yellow fever patients from Fort Jefferson between 1890 and 1900. The Fort Jefferson Post Cemetery once held the graves of dozens of people, most of them being U.S. soldiers. The hospital's underwater location shows the impact of climate change and storm events on the Florida Keys. Archaeologists are still working to learn more about the people interred at the cemetery.
