 Researchers suspect that natural disasters caused the Taposiris Magna temple to collapse. | Archaeologists in Egypt have discovered an underground tunnel at Taposiris Magna, a temple dedicated to Osiris, the god of death. Part of the tunnel is submerged underwater, which could be the result of several earthquakes that struck the region between 320 and 1303 C.E. Cleopatra ruled Egypt from 51 until she and Mark Antony died by suicide in 30. Historians believe they are likely buried together, but their graves have never been found. |  |
