DiningRoom 72dpi 860wThe Dining Room was designed in the French Renaissance style. The Flaglers entertained large parties in this room for lengthy, elegant dinners. Flagler sometimes held dinners in the Dining Room for his male associates, hosting prominent men from financial, literary, and legal circles.

The rug was specially woven for the room and is recessed into the parquet floor. The wall coverings are green silk, reproductions of the original fabric. Like the Library, the Dining Room ceiling is cast plaster painted to look like wood. Inset into the "wooden" beams are rosettes incorporating romanticized dolphin creatures. One of the room's most prominent features, the fireplace mantle, incorporates elaborately carved culinary references such as shells, crabs, and fruit.
