19th century hospital, cemetery found underwater off Florida Keys

Archeologists discovered the remains of a 19th century quarantine hospital and cemetery submerged in the waters off the Dry Tortugas National Park in the Florida Keys, officials said Monday. 

The small hospital was used to treat yellow fever patients at Fort Jefferson between 1890 and 1900, the National Park Service said in a press release. Dry Tortugas staff conducted a survey in August of 2022 that led to the findings. 

Only one grave has so far been identified at the underwater Fort Jefferson Post Cemetery, according to the NPS. Dozens of people, mostly soldiers stationed at the fort, may have been buried there.
