Montana had a 16-year career as a quarterback, 14 of which were with the San Francisco 49ers, where he won four Super Bowls. For the last two seasons of his career he played for the Kansas City Chiefs. Montana was selected to eight Pro Bowls, was twice named most valuable player by the Associated Press and was awarded “Sportsman of the Year” and named the No. 1 clutch quarterback of all time by Sports Illustrated. The 49ers retired his number in 1997. Montana was inducted into the Pro Football Hall of Fame in 2000.

Dubbed “Villa Montana,” the estate consists of 500 acres with a main house, two guesthouses, an equestrian facility, a 30-stable barn, several ponds and a Tuscan olive grove that produces several dozen gallons of olive oil each year. “It was a long search in finding the right property,” Hayden said. “Their siting of the home is one of the most spectacular views of Mount St. Helena — yet it’s really a family home. It’s an elegant home with very intimate spaces.”

The main building is a 9,700-square-foot three-bedroom, three-bath house with ornate stonework, tiled floors, elaborate chandeliers and wrought-iron torchieres to emphasize the Mediterranean-style design intent of the home.

An on-site equestrian riding facility, 30-stable barn and numerous riding trails on the 500 acres can accommodate everything from a hobbyist horse owner to a professional trainer.

The property also has a pool, skeet shooting range, sport court for tennis and basketball, 3,500-bottle wine cellar and spacious outdoor kitchen with wood-fired oven, Tuscan grill and wine-chilling station.

The couple also is selling an adjoining 87-acre ranch, with 11-stable barn, for $3.1 million.
