This antebellum mansion was home to Major Robert Gamble and headquarters of an extensive sugar plantation. It is the only surviving plantation house in South Florida. In 1925, the house and 16 acres were saved by the United Daughters of the Confederacy and donated to the state. Today, the mansion is furnished in the style of a successful mid-19th century plantation. Guided tours of the Gamble Mansion are given six times a day, Thursday through Monday and there are picnic tables on the grounds. The visitor center is open from 9am - 11:45 am and 12:45 pm - 5pm, Thursday through Monday.
