London heard a very special gun salute on the day to mark her birthday, and it is the first time Her Majesty has been afforded this honour, which is reserved for the King and Queen on their birthdays.
In a press release from the British Army, it was announced: "The King’s Troop Royal Horse Artillery will fire a 41 Gun Royal Salute from 1200hrs" and "The Honourable Artillery Company will fire a 62 Gun Royal Salute from Tower Wharf, 17 July 2023, from 1300hrs."
Dog walkers were even advised to avoid the area because the loud noise could have startle pooches.
Camilla has received birthday wishes on Instagram from the Prince and Princess of Wales as well the main Royal Family account.
Prince William and Princess Kate said: "Happy birthday to Her Majesty the Queen," alongside a photograph of Camilla smiling away at Wimbledon – a shot that was taken earlier this week during her visit.
The official Royal Family Instagram account opted for a trio of images of Her Majesty smiling, writing: "Wishing Her Majesty The Queen a very Happy Birthday today!"
Last year, Camilla marked her landmark birthday with a new portrait alongside her beloved Jack Russell Terrier, Beth.
The beautiful image was captured by royal photographer Chris Jackson. Wearing an elegant summer dress complete with a feminine V-neck collar adorned with blue and pink flowers, the then-Duchess Camilla was pictured in the gardens of her Wiltshire home.
Speaking about the opportunity, Chris said: "Really special to photograph the Duchess of Cornwall at her home in Wiltshire for her 75th Birthday. I’ve spent many years travelling around the world photographing The Duchess on Royal Tours and engagements so it’s lovely to photograph her somewhere she feels so relaxed. I love the fact she even grew the impressive peaches in the photo."
The Queen's 76th birthday celebrations come after the news that she will not receive her own annuity from Parliament, despite the previous consort, the late Duke of Edinburgh, being paid nearly £360,000 to fund his official duties.
An official report into the royal household’s finances confirmed Camilla's activities will be met by the Sovereign Grant instead, and she will not be given a separate payment.
It read: "Parliament provided Prince Philip with a separate annuity worth £359,000 per annum. Queen Camilla will not receive a separate annuity and the Queen's activities will be funded from the Grant."
