 The most prominent features of Kingsley Plantation are the owner's house—a structure of architectural significance built probably between 1797 and 1798 that is cited as being the oldest surviving plantation house in the state—and an attached kitchen house, barn, and remains of 25 anthropologically valuable slave cabins that endured beyond the U.S. Civil War (1861–1865).The foundations of the house, kitchen, barn and the slave quarters were constructed of cement tabby, making them notably durable.Archeological evidence found in and around the slave cabins has given researchers insight into African traditions among slaves who had recently arrived in North America.
