This is the Levant Mine. Also nicknamed the mine under the sea. It was first opened in 1820, and would eventually reach 2000 feet deep into the earth. But also a full mile underneath the Atlantic Ocean. I’m sure you can imagine what might happen if one of the tunnels were to fail. Incredibly, that isn’t even the worst of the conditions within. This is the story of the Levant Mine Disaster. As always, viewer discretion is advised.
