"People variously called the house a castle, a mansion, a palace. But it reminded me of the badger sett," Prince Harry wrote. "Dark, claustrophobic. I walked around saying, ‘The King lived here, you say? Really?’"

Elvis lived at Graceland from June 26, 1957, until his death Aug. 16, 1977.

In the book, Prince Harry quipped that whoever picked out the decor of the famous residence must have been on drugs.

Prince Harry recalled, "I stood in one tiny room with loud furniture and shag carpet and thought, ‘The King’s interior designer must have been on acid.’"
