Alexandria

Alexandria, Egypt stands as one of history's greatest archaeological mysteries, where the legendary tomb of Alexander the Great remains hidden beneath centuries of civilization. This ancient city, founded by the conqueror himself in 331 BCE, once served as the glittering capital of Ptolemaic Egypt and continues to reveal its secrets through underwater excavations and underground tunnels. Following Josh Gates' thrilling investigation, visitors can explore the same coastal waters and historic districts where cutting-edge archaeology meets ancient wonder.

Alexandria is Egypt's second-largest city and principal Mediterranean seaport, extending approximately 40 km (25 mi) along the northern coast at the western edge of the Nile Delta. Founded by Alexander the Great in 331 BC, the city became the capital of Ptolemaic Egypt and one of antiquity's most important cultural and intellectual centers. Today, Alexandria is a modern metropolis with a population of approximately 6.1 million, where ancient ruins lie beneath busy streets and submerged offshore. Gates investigated the city searching for one of archaeology's greatest prizes: the lost tomb of Alexander the Great, diving coastal waters to explore sunken remains of the ancient Royal Quarter and tunneling beneath the modern city despite equipment challenges.

What Experts Say

Alexandria served as the capital of Ptolemaic Egypt and remained one of the Mediterranean's leading cities for nearly a millennium, renowned for the Great Library and the Pharos lighthouse. Ancient sources confirm that Alexander's body was brought to the city after his death in Babylon in 323 BC and placed in a magnificent tomb, which became a pilgrimage site for Roman emperors and dignitaries. However, the tomb's location was lost sometime in late antiquity, and no modern excavation has definitively identified it, making this one of archaeology's most enduring mysteries.

Mainstream archaeologists have proposed numerous theories about the tomb's fate. Some experts believe it may have been destroyed during religious riots in late antiquity, while others suggest it could lie beneath the modern city, buried under centuries of urban development. The ancient Royal Quarter, where historical sources placed the tomb, is now partially submerged due to earthquakes and coastal subsidence. Underwater archaeologists have mapped extensive ruins offshore, and these submerged remains represent a significant area of investigation, though connecting specific structures to Alexander's tomb requires conclusive evidence that has proven elusive.

Gates' investigation in Alexandria explored both the submerged coastal ruins and underground spaces beneath the modern city, consulting with experts about the challenges of searching a continuously inhabited urban area. The episodes highlighted the legitimate archaeological debate about whether the tomb survived into the modern era or was lost centuries ago. Alexandria's transformation from ancient capital to modern metropolis, combined with natural disasters that reshaped the coastline, means that even if the tomb survived, locating it requires navigating both physical obstacles and thousands of years of urban layers.

The search for Alexander's tomb represents a case where historical sources confirm the tomb's existence and general location, but physical evidence remains frustratingly out of reach. Gates' investigation documented the real challenges archaeologists face: limited access in a densely populated modern city, submerged ruins requiring specialized diving, and the reality that some ancient mysteries may remain unsolved despite our best technologies and intentions.
