Tora, Egypt

Egypt announced on Jan. 2 the recovery of a sarcophagus lid dating back nearly 2,700 years that it said had been smuggled out and put on display at a museum in the United States.

Egyptian Foreign Minister Sameh Shoukry announced the recovery of the artifact, known as the "Green Sarcophagus," during a televised press conference.

The secrets behind the construction of the oldest and only survivor of the Seven Wonders of the World have been locked within its limestone and granite walls for centuries. But now archaeologists believe they have finally uncovered how Egyptians were able to lug millions of 2.5 ton blocks 500 miles to create the Great Pyramid of Giza, reported Mirror Online on Sept. 24.
