Ramesses II was the most powerful pharaoh to rule Egypt, and his construction of a new capital city, Pi-Ramesses, was his crowning achievement. It was the biggest building program since the pyramids, but somehow, this metropolis completely vanished from history. What happened? Where did it go? And to begin with, where was it built? Join host Adam Mastrelli as we follow the brilliant detective work that may have uncovered the mysterious fate of this magnificent city.

Over 1,000 years ago, a great civilization built a thriving metropolis that was larger than medieval Paris, London and Rome. At its heart was a pyramid that rivaled those of Egypt. But this mighty city was not in Europe or anywhere in the East. It was in North America. Join us as we explore ancient Cahokia, one of the most astonishing mysteries of Western archeology. Using cutting-edge technology, we unravel its secrets and reveal the turbulent events that marked the dramatic rise and fall of America's first great city.
