To mark the Prince of Wales' 70th birthday, this year's special exhibit will feature a curated collection of the Prince's favorite art works and collectible pieces that include a cloak belonging to Napoleon Bonaparte, taken from his carriage immediately after the Battle of Waterloo in 1815.
Prince Charles curated the exhibition himself and even included some of his own art works.
Rows of paintings fill the walls, while tables are filled with books, vases, trinkets and family photographs.
"They both agreed there was little they could do but they are very, very annoyed", a palace insider tells the publication. The sweet photo is usually displayed at Charles' country home, Highgrove House.
And to give it even more of a personal touch, non of the pieces have explanatory text next to them to create more of visual display rather than a museum feel.
The exhibition called "Prince and Patron" will be open to the public until September 30.
As well as supporting the Queen, Charles has become known for his charitable work, his founding of the Prince's Trust, and his campaigning on the environment and other issues.
In the audio commentary, Charles says: "I am very fond of the two preparatory oil sketches of my sons which I acquired from the artist, Nicky Philipps, in 2009". Buckingham Palace has also commissioned a range of souvenirs for fans of the royal family to purchase - including a gold embellished pram with faux pearl detailing and "Royal Baby 2018" stitched on the back that neatly matches the shoes.
