However, you might have struggled to see him as he took his seat this morning.
Sat on the third row of guests, the King’s son was awkwardly obscured by the feather sticking out of the hat of his aunt Princess Anne.
The large red plume was on top of the ceremonial hat worn by the Princess Royale, perfectly hiding Harry’s face throughout the service.
And it didn’t go unnoticed by royal fans who took to Twitter to point out the awkward moment adding that Harry and his wife Meghan Markle, who was absent from the ceremony today, suffered a similar fate at the Queen’s funeral.
The couple had previously had their view blocked by a candle at the state funeral back in September last year.
Taking to Twitter, one wrote: “Prince Harry is hidden behind the feather on Princess Anne’s hat… last time it was a candle.”
Another joked: “Thank you princess Anne for such a well placed feather.”
While a third added, “Princess Anne’s feather is the new candle!”
The Duke of Sussex, 38, walked without brother William but was accompanied by Princess Beatrice’s hubby Edo Mapelli Mozzi.
He then took a seat in the third row of royals next to Princess Eugenie’s husband Jack Brooksbank.
On his other side is Princess Alexandra, 86 — Queen Elizabeth’s cousin.
Alongside is Prince Andrew’s daughters Eugenie, 33, and sister Beatrice, 34, who is sitting next to Edo.
In front of Harry is his aunt Princess Anne alongside her husband Vice Admiral Sir Tim Laurence.
In the front row are the Prince and Princess of Wales and their children, and Prince Edward and his wife Sophie Wessex.
A source told The Sun: “There were discussions that the seating could be arranged on line of succession.
“But that would have put fifth-in-line Harry front and centre — and with William and Kate.
“Instead the decision was working royals only at the front and work back from there. Harry will be a long way from his father.”
Prince Harry – wearing a dark morning suit and medals – is attending without wife Meghan, 41, or children Archie, who turned four today, and Lilibet, one.
The Duke touched down in the UK on Friday and is expected to jet home to California just two hours after the service.
An insider told The Sun: “He’ll be in and out of the UK in 24 hours.”
Charles and Camilla arrived at Westminster Abbey following a spectacular 1.42 mile journey in the air-conditioned Diamond Jubilee state coach, built in 2012.
They left Buckingham Palace accompanied by the Sovereign’s Escort of the Household Cavalry, before passing a guard of honour of around 160 members of the three armed services.
The pair were flanked by over 1,000 members of the Armed Forces before passing a 100-strong guard from the Royal British Legion in Parliament Square.
The service will run for around two hours where ancient traditions – some dating back to 1065 – will see Charles anointed and crowned with the 1661 St Edward’s crown.
The service will end at around 1pm before the royals set off on a 1.4 mile procession back to Buckingham Palace.
The King, Queen, Prince and Princess of Wales and their three children will ride in the 260-year-old, four-tonne Georgian-era Gold State Coach.
Charles is the first king to be crowned in Britain since his grandfather King George VI on May 12, 1937.
He is the 40th monarch to be crowned at Westminster Abbey, with the first thought to be Harold Godwinson in 1065.
Much like his beloved Mama, Charles has also broken with tradition.
Fuelled by a desire for a stripped-back monarchy, the King has shunned the extravagant trappings of wealth seen in his own mother’s £1.57million ceremony.
The guestlist has been slashed to just 2,000, compared to the Queen’s 8,250, and the length of the service has been drastically reduced.
Even the dress code is different, with the King opting to wear military uniform instead of the silk stockings and breeches seen in the past.
