The Queen was just 27 when she walked into Westminster Abbey for her coronation, months after she actually took over as Monarch.
To support her on that big day on June 2, 1953, the Queen picked six maid of honours to stand by her side.
Each was an unmarried daughter of an earl or a duke, and they had important tasks during the ceremony including holding her robes.
They were all understandably under a lot of pressure, and were desperate not to put a foot wrong as millions of people watched on from around the world.
Each of the women was given a bottle of smelling salts on the day in case they started to feel faint, but according to maid of honour Lady Glenconner they weren't much use.
She very nearly fainted during the event, but thankfully a member of the congregation came to her rescue.
Speaking on ITV's The Queen: Inside the Crown documentary, she explained that she kept her little file of salt in her glove.
She said: "Not that they did much good.
"I started to sway, everything was black. I couldn't see, everything was black. It was awful.
"I thought I can't let the Queen down.
"I could ruin the whole thing. All the cameras, millions of people all over the world watching.
But thankfully, one of the Queen's ushers Black Rod noticed what was happening and steadied her.
She said: "He kept me just long enough for me to recover."
Lady Glenconner also recalls the moment she saw the Queen for arrive for the ceremony.
She said: "I remember standing at the door and I suddenly heard this roar, and we know she was coming.
"The roar got louder, and louder and louder.
"The colour and music was like a Disney film, it was absolutely unreal."
Speaking about the moment they stepped onto the Buckingham Palace balcony to wave to well-wishers, she said: "The noise, the love was a physical thing.
"It hit you, you could feel it. It was the most marvelous thing I've ever done in my life."
