Alexandria ranked as the ancient world's second greatest city after Rome, home to 500,000 people, a legendary library, and famous lighthouse. Here stood the Caesareum—a temple honoring deified Julius Caesar with grand colonnades, libraries, and banquet halls. Two massive 200-ton obelisks from Heliopolis (Cleopatra's Needles) once flanked its entrance; one now stands in London's Victoria Embankment, the other in NYC's Central Park. Yet the temple itself lies buried beneath Alexandria—guests at the Hotel Metropole literally sleep above its ruins, and the ancient metropolis remains largely hidden under apartments, hotels, and warehouses.
