Kingsley Plantation
Built in 1792 by Zephaniah Kingsley, a landowner who produced Sea Island cotton, citrus, sugarcane, and corn with the aid of about 60 slaves, this is the oldest remaining cotton plantation in the state. Take a self-guided tour of a barn and 23 tabby (a concretelike mixture of sand and crushed shells) slave houses to learn about the lives of the people who labored here. Weekend open-house hours are available, yet limited from 10 am to 12 pm and 1 pm to 4 pm to protect the structure.
