When Priscilla Presley opened Graceland, the home of her ex-husband, Elvis Presley, to the public on June 7, 1982, she had no idea how many people would come. To her surprise, the 3,000 tickets available to visit Graceland the very first day sold out. And now, almost 40 years later, Graceland is one of the most visited private homes in the United States. Graceland receives around 600,000 visitors each year, compared to The White House and The Biltmore Estate which both receive approximately 900,000 visitors per year. In 2016, Graceland welcomed their 20-millionth visitor.
