The royal has been interested in the artform since he was a young child, and during his youth he painted his parents, the late Queen and Prince Philip. When these pieces went to auction they fetched £46,000, so it's no surprise that Charles is actually one of the UK's most successful living artists.
WATCH: Relive the moment King Charles unveiled his first official portrait
The Telegraph reported back in 2018 that the monarch had made £2 million from sales of his paintings. However, despite this small fortune, the King has donated all proceeds from his hobby to the Prince of Wales's Charitable Fund.

Charles follows in his father's footsteps when it comes to his artistic endeavours as the late Duke of Edinburgh also enjoyed getting behind the easel. One expert said Philip's paintings were "exactly what you'd expect – totally direct, no hanging about".
Art runs in the Windsor family and when Charles' pieces were first featured in an exhibition at Windsor Castle, they sat alongside artworks from Prince Philip and Queen Victoria.
Philip was known to be quite artistic
Below, we have gathered some of the King's finest pieces of works, so have a scroll through and enjoy…
1/9
Castle Mey
Charles is a fan of watercolours and one of his earliest works is Castle Mey, which his grandmother, the Queen Mother owned. Charles was close with her and he painted the stunning photo while on the estate's grounds in Caithness.

Balmoral
The monarch has also captured his late mother's favourite home of Balmoral in Aberdeenshire. Despite the incredible castle being off in the distance, Charles still captured the Union Jack flying high and the trees surrounding the grounds.
3/9
Highgrove
It wasn't just Scotland that the King painted, as has also captured still moments at his Gloucestershire home of Highgrove. In this painting, seen at an exhibition, Charles has beautifully painted his patio, a deck chair and a unique stone ornament while the garden behind flourishes with trees and flowers.

Mountains
Charles favoured natural scenes over portraits and this extraordinary image captures the snow-capped mountains around Scotland.

Stamps
In 1994, the Royal Mail drew attention to the then Prince of Wales's talents with a series of commemorative stamps that featured his artworks. This gorgeous piece pictured is of Dersingham, Norfolk, which is located near Sandringham.

Sandringham
Charles has also captured the elegant Sandringham building in its full glory. His portrait sees the brick building glistening in the sunlight and the domed rooves of the royal property.

Scotland
Charles didn't just paint at the royal residences, but he has painted many other portraits of Scotland. This amazing image really captures the quietness of his surroundings.

Exhibitions
The King's artworks have been displayed at numerous exhibitions, sometimes alongside those painted by the late Duke of Edinburgh and Queen Victoria. Here, we can see two pretty natural artworks from different seasons.

Ski pass
Alongside commemorative stamps and exhibitions, the monarch's artworks have also been used on ski passes. The King and his family used to holiday at the Klosters ski resort in Switzerland where he painted the surrounding landscapes. Lucky skiers in 1997 got to use his artwork of the mountain and trees at the resort.
