Prince Charles and Camilla, the Duchess of Cornwall just recently celebrated another relationship milestone. Earlier this week, the royal couple reportedly marked their 15th wedding anniversary alone together amid the COVID-19 crisis in the United Kingdom.

The celebration was in time as they just both got reunited after they observed a strict quarantine. The Prince of Wales had tested positive for the virus, which then required his wife to undergo a 14-day quarantine.

Fortunately, the Cornwall couple has reportedly remained "in good health." Hence, they are now back to their works and duties despite having to stay inside their Scottish home, Birkhall.

As per reports, Prince Charles has set up a remote workplace inside his home. He became the first royal to accomplish a royal engagement via video link when he opened the NHS Nightingale Hospital.

Aside from the speech he gave during the engagement, he also shared a few more messages through a video, especially after he got out of isolation. The video messages were all recorded inside his home office. So, fans and followers were quick to notice the details of the interior of his Birkhall workplace.

According to Hello! magazine, several photos of members of the British Royal Family can be seen in frames inside the office. But, among all these photos, one reportedly stood out the most since it featured the Sussex couple and the Cambridge family.

As reported, it was a photo taken during Prince Louis' christening in 2018, during which time Meghan Markle and Prince Harry are still active as senior working royals. Aside from the two families, Prince Charles and Camilla, the Duchess of Cornwall, are also in the shot beside the Duke and Duchess of Sussex.

The publication also shared that the photo was taken inside the Clarence House in the Morning Room. It was also described as a "beautiful family portrait," which is why it was easily spotted.

In a scoop released by Cheat Sheet, it was said that the family portrait was also accompanied by other "rare" and beautiful photos of other members of the Royal Family. This included a solo photo of Prince Charles and Prince George, which seemingly appeared to be taken in 2015 for Earth Hour.

There was also a photo of the Prince of Wales, alongside his wife, during their wedding in 2005. An image of a young Princess Anne was also seen inside the office.

Princes Harry and William also have a special shot during their father's 70th birthday. As for the remaining photo, it was said that it featured Camilla's children, who were beside their respective partners.
