What’s believed by historians to be the oldest plantation house in the state of Florida can be found just north of Jacksonville.

Situated on the uppermost tip of Fort George Island is the Zephaniah Kingsley Plantation Home and Buildings, better known as the Kingsley Plantation. While most of the original 1000-acre plantation is now forest, 60 acres containing the house and slave quarters are preserved and maintained by the U.S. National Park Service.

According to experts, the owner’s house was likely constructed sometime in the late 1790s.

Closed during the week for structural work, visitors can see inside the house on weekends. Tours are available on a limited basis and reservations are recommended.

The grounds, which include slave quarters, barn, waterfront, and interpretive garden, are open seven days a week from 9am-5pm. Admission is free.
