For over 400 years, the disappearance of 117 colonists from Roanoke Island has been America's oldest mystery. Now, a mysterious stone inscription may lead to uncovering the truth. Expert stonemason Jim Vieira team has been investigating the mystery to find out what happened to the lost colony.

Stonemason and historical detective, Jim Vieira, studies the ancient ceremonial structures of North America including mounds, walls and star cities, as well as the archeological evidence for giants that existed in ancient America.

Jim also likes to track down giants. He believes that there may, at some point, have been a race of people who were more than seven feet tall, perhaps had two rows of teeth, and lived in America.
