A sunken red granite tower, part of a pylon of the Isis temple is loaded on a truck after being extracted out of the Mediterranean Sea off the archaeological eastern harbor of Alexandria, Egypt Thursday, Dec. 17, 2009. Egyptian archeologists have lifted a major artifact out of the Mediterranean Sea in an elaborate effort to highlight ancient treasures buried under water off the harbor in Alexandria. It is intended to be the centerpiece of a planned underwater museum Egypt hopes will draw tourists to its northern coast, often overshadowed by hotspots such as Luxor, the Giza pyramids and Red Sea beaches. Archaeologists on Thursday hoisted a 9-ton temple pylon from the waters of the Mediterranean that was part of the palace complex of the fabled Cleopatra before it became submerged for centuries in the harbor of Alexandria. The pylon, which once stood at the entrance to a temple of Isis, is to be the centerpiece of an ambitious underwater museum planned by Egypt to showcase the sunken city, believed to have been toppled into the sea by earthquakes in the 4th century. Divers and underwater archaeologists used a giant crane and ropes to lift the 9-ton, 7.4-foot-tall pylon, covered with muck and seaweed, out of the murky waters. It was deposited ashore as Egypt's top archaeologist, Zahi Hawass, and other officials watched. The pylon was part of a sprawling palace from which the Ptolemaic dynasty ruled Egypt and where 1st Century B.C. Queen Cleopatra wooed the Roman general Marc Antony before they both committed suicide after their defeat by Augustus Caesar. The temple dedicated to Isis, a pharaonic goddess of fertility and magic, is at least 2,050 years old, but archaeologists believe it's likely much older. The pylon was cut from a single slab of red granite quarried in Aswan, some 700 miles (more than 1,100 kilometers) to the south, officials said. "The cult of Isis was so powerful, it's no wonder Cleopatra chose to make her living quarters next to the temple," said coastal geoarchaeologist Jean-Daniel Stanley of the Smithsonian's National Museum of Natural History. Egyptian authorities hope that eventually the pylon will become a part of the underwater museum, an ambitious attempt to draw tourists to the country's northern coast, often overshadowed by the grand pharaonic temples of Luxor in the south, the Giza pyramids outside Cairo and the beaches of the Red Sea. They are hoping the allure of Alexandria, founded in 331 B.C. by Alexander the Great, can also be a draw. Cleopatra's palace and other buildings and monuments now lie strewn on the seabed in the harbor of Alexandria, the second largest city of Egypt. Since 1994, archaeologists have been exploring the ruins, one of the richest underwater excavations in the Mediterranean, with some 6,000 artifacts. Another 20,000 objects are scattered off other parts of Alexandria's coast, said Ibrahim Darwish, head of the city's underwater archaeology department.
