Tell the entrance guard you were there to see the "Last Supper" stained-glass window show, and you were allowed to roam a portion of the catacombs for about 10 minutes before anyone hassled you.
But those open sections are only a fraction of the sprawling building that rises many stories and plunges deep underground.
So wherein lies the King of Pop in the monolith? That may be a secret for the ages.
On Friday, a tourist family asked a guard whether the superstar's tomb was private. The guard said it was.
"Private ... forever?" one of them asked.
"Private forever." he said.
No fans, no paparazzi, and so far no one trying too hard to steal a glimpse of the vault containing Jackson's golden casket.
The exact location may forever remain unknown to all but a select few: A guest who attended the Jackson ceremony told The Associated Press the casket had not been put into the vault by the time mourners left.
The guest spoke on condition of anonymity because of the sensitivity of the day.
Under Friday's hot midday sun, a woman with a camera was denied entry to the mausoleum. Guards shooed away a radio reporter who tried to go inside then began interviewing people outside.
The funeral began Thursday night nearly two hours after its scheduled 7 p.m. time. Some 200 mourners, including 77-year-old Elizabeth Taylor and other celebrities associated with Jackson, showed up promptly, only to wait at the outdoor seating area, under a withering late-summer sun that pushed temperatures to 90 degrees even as it was going down.
The ceremony began with remarks and song after the family arrived to fill the front five rows of white folding chairs.
Mourners then followed Jackson's brothers as they carried the casket into the mausoleum. The singer's daughter, 11-year-old Paris, cried and was comforted by her aunt, LaToya.
Paris and brothers Prince Michael, 12, and Prince Michael II, 7, known as Blanket, began the service by placing a bejeweled crown on their father's casket. They were composed through most of the 90-minute ceremony, the guest said.
Once inside, Gladys Knight performed the hymn "Our Father" (The Lord's Prayer) and moved many to tears, according to the guest. When it was over, many of the 200 mourners hugged each other. Among them were Taylor, Jackson's ex-wife Lisa Marie Presley, Barry Bonds and Macaulay Culkin.
