CHARLESTON, S.C. (AP) - You might call it the foundation of South Carolina.
Scientists have found a floor thought to be 320 years old at Charles Towne Landing, the site of the first permanent English settlement in South Carolina
The foundation is the oldest archaeological remains found at the site on the Ashley River. It is made of tabby, a material of that day made of lime and oyster shells.
Scientists think the floor dates to 1690, just after the colonists moved from the site to the Charleston peninsula where the center of Charleston stands today.
