Queen Elizabeth II of the United Kingdom has revealed her personal views on her coronation in a rare televised interview, describing one of the crowns she wore as so heavy “your neck would break off.”

In a 2018 BBC program on the 65th anniversary of her coronation, the monarch made the remarks.

As the two study the Imperial State Crown and view footage of the Queen’s Coronation in 1953, Alastair Bruce, an expert on the Crown Jewels, reportedly comments, “You have to keep your head very still.”

The Queen agreed, saying, “Yes.” “And you can’t look down to read the speech you have to take the speech up.

“Because if you did your neck would break, it would fall off.

“So there are some disadvantages to crowns, but otherwise they’re quite important things.”

On June 2, 1953, Elizabeth, aged 27, was crowned in front of a large crowd, just over a year after her father, King George VI, died of lung cancer.

Britain’s longest-reigning monarch talked frankly about the historic event 65 years ago in an hour-long BBC documentary, detailing how the Imperial State Crown is studded with diamonds and other valuable stones, making it “very heavy.”

“Fortunately my father and I have about the same sort of shaped head. But once you’ve put it on it stays, I mean it just remains itself,” The Queen stated in the BBC program.

“You can’t look down to read the speech, you have to take the speech up. Because if you did your neck would break, it would fall off. So there are some disadvantages to crowns, but otherwise they’re quite important things,” she said.

She was crowned with the St. Edward’s Crown, which had previously been worn by George V and George VI at their coronations.

The crown, which weighs 2.23 kilograms (4.9 pounds), was named after Edward the Confessor and is on display at the Tower of London’s Jewel House.

According to The Sun, Queen Victoria chose a smaller crown because she was concerned about the weight of the St. Edward’s Crown.

The footage is part of an hour-long BBC One documentary The Coronation, and contains behind-the-scenes footage of the Queen, capturing her sense of humour and life at the palace, according to the UK’s The Telegraph.

The 91-year-old monarch reportedly said that riding in the magnificent golden chariot to the event at London’s Westminster Abbey — the site of every coronation since 1066 — was “horrible”

“It’s not meant for traveling in at all. I mean it’s only sprung on leather. Not very comfortable. It can only go at walking pace. The horses couldn’t possibly go any faster. It’s so heavy,” the Queen said.

According to the Royal Collection Trust, the crown is studded with 2868 diamonds, 11 sapphires, 11 emeralds, and 269 pearls.

Describing the crown as “unwieldy”, The Queen said: “You can’t look down to read the speech, you have to take the speech up.

“So there are some disadvantages to crowns, but otherwise they’re quite important things.”

At a press screening of the documentary, Bruce told reporters that the Queen appeared at comfortable with the Crown Jewels, even grasping a table on which the crown was sitting and bringing it closer.

He recalled her saying, “Well, you know, it’s my crown.”

“She was very practical with the Crown Jewels in a way I wasn’t quite expecting.”
