In the middle of foundation work for the new Gaillard Auditorium, construction workers found something totally unexpected: 37 unmarked graves in the soil where Charleston's big performance hall was about to be built. The city immediately put the project on hold while archaeologists searched for clues to the bodies' age and identity. To the best of their knowledge, the bodies were buried in a cemetery at the site between 1680 and 1740. Of the 37 sets of remains, 31 were adults, three were children, and one was an infant. At least five were males and five were females. Beyond that, the mystery of the Gaillard bodies remains largely just that — a mystery. Got any leads?
