The Casements' property was originally nine acres that stretched east from the Halifax River to the present day Halifax Drive, with a private trail and right-of-way to the Atlantic Ocean. Rockefeller employed a Swedish landscape designer to develop the gardens to his own specifications. Extensive renovations were done in 2009 to create Rockefeller Gardens. A promenade along the river entices people to stroll or take their daily exercise. An outdoor stage is used for weddings, and free movies are shown there on the first Friday of the month. A recent addition to the water pond on the grounds is a fountain with a sculpture of a silver king tarpon, Megalops Atlanticus.
