A tunnel found under Egypt’s Taposiris Magna Temple could lead to the long lost tomb of Cleopatra, it’s hoped. The carved rock tunnel—described as a “geometric miracle”—was found at the shrine near Alexandria, which was once the nation’s capital. Archaeologist Kathleen Martinez of the University of San Domingo has long believed that Cleopatra, the last pharaoh, could be buried below the temple, adding that finding her remains would be “the most important discovery of the 21st century.” “If there’s a one percent chance that the last queen of Egypt could be buried there, it is my duty to search for her,” Martinez previously said. “This is the first time that any archeologist has found tunnels, passages underground [and] inside the enclosure walls of the temple, so we have changed forever what they know about the architecture.”
