When Elvis lived there, Graceland was a private home. He shared the mansion with other members of his family, notably his aunt, Delta Presley Biggs. After his death, Delta continued living in the estate. It wasn't until five years later that the house became opened to the public as a museum.
However, not all of the rooms were available for exploration. Aunt Delta still called the place home, and although she didn't need the whole mansion, one room was essential to her - the kitchen. It remained off-limits to the public until 1993 when Delta passed away.
