Don't be confused. It took me a little while to figure it out. The Charles Deering who established the Deering Estate was the brother of the James Deering who built Vizcaya Museum and Gardens. Two Miami landmarks, two millionaire brothers/industrialists/philanthropists. Charles Deering was the son of William Deering, founder of Deering Harvester Company. After graduating from the U.S. Naval Academy and serving as an officer in the Navy until 1881, he became secretary of his father's company, which merged with McCormick Harvesting Company and became International Harvester in 1902. He died at the age of 75 at his estate at Cutler. He lived on the 444-acre property for five years, from 1922 until his death in 1927. Located at 16701 Southwest 72nd Avenue in the Cutler neighborhood of Palmetto Bay, the estate, which is listed on the National Register of Historic Places, consists of a three-story wooden house built in 1900, known as the Richmond Cottage, and a three-story stone mansion. The grounds include what is thought to be the largest virgin coastal tropical hardwood hammock in the continental United States. The Richmond Cottage was built as a family home at the end of the 19th century, converted into a 22-room hotel in 1900, then purchased by Charles Deering in 1916 and used as his residence until his Mediterranean Stone House was completed in 1922. It has 18-inch poured concrete walls, oolitic limestone, coffered ceilings, copper clad and brass doors, an elevator and a wine cellar. Deering intended the house to be used as a showcase for his art collection and books. Two other must-see attractions on the property are the Cutler Burial Mound, one of the few surviving prehistoric mounds in Miami-Dade County, and the Cutler Fossil Site, a sinkhole that was discovered in 1979 that was found to contain bones of Pleistocene animals and bones and artifacts of early humans.
