Fox History, Sunday, 10 p.m.

A journey to discover the legendary lost city of Piramesse. This magnificent ancient capital was built 3,000 years ago by the Egyptian pharaoh Rameses. But long ago the whole city disappeared. When it was finally rediscovered by early archaeologists, it opened up a bizarre puzzle — because when Piramesse was finally found, it was in the wrong place — a place where Ramesses could not have probably built it.
