In a few years, you may be able to see Alexandria the way it once was — deep beneath the sea. The areas of classical Alexandria that contained the ancient world's biggest library along with Cleopatra's palace have sunk beneath the waves, but now it looks as if the United Nations may step in and help Egypt show off these structures in a unique underwater museum (architectural drawing above). Above the water, the museum will have illuminated sail-like structures and be connected to the mainland via fiberglass tunnel. Want to gawk at some of the underwater treasures that museum visitors might see? This is a statue of a priest of Isis, standing among fallen columns. Though this statue was pulled out of the water in the late 1990s, there are many other sculptures like these still underwater. This gorgeous art, along with the city's famed lighthouse, made Alexandria a favored tourist spot for Romans on holiday over 2,000 years ago. Here's another glimpse inside Cleopatra's palace, where you can see the marble head of Roman princess Antonia Minor. The great buildings of Alexandria were destroyed by earthquakes, and then by encroaching waters. Photos via National Geographic. Underwater Museum for Egypt Sunken Treasures?
