Little is known about the interiors of one of the private royal residences on the Norfolk estate, Sandringham House, but Prince Harry once reflected his negative thoughts about the property in his memoir, Spare.

While his traditions may have changed now and he hardly spends time in the UK, Harry is left with the memories of his childhood experiences at King Charles' private estate, which previously belonged to Queen Elizabeth II.

The Duke of Sussex once shared details about the private royal residence in his book, Spare, describing it as "a jail cell".

He wrote: "The dining room at Sandringham, for instance, was our version of Dante's Inferno. Much of Sandringham was balmy, but the dining room was subtropical. Pa and I would always wait for Granny to look away, then one of us would jump up, sprint to a window, crack it an inch. 'Ah, blessed cool air.' But the corgis always betrayed us..."

Prince Harry further added: "The cool air would make them whimper, and Granny would say 'Is there a draft?' And then a footman would promptly shut the window. (That loud thump, unavoidable because the windows were so old, always felt like the door of a jail cell being slammed)."

The late Queen Elizabeth II marked several milestone occasions at the property, including her first televised Christmas message in 1957 and the eve of her Platinum Jubilee just seven months before she died in 2022.

Every Christmas, King Charles and Queen Camilla continue to lead the family to the service at St Mary Magdalene church on the estate on the morning of Christmas Day.

It originally cost £220,000 and then had 29 bedrooms, with 5,500 acres of land, as noted in royalpalaces.com. Currently, the exact number of bedrooms is undisclosed, but there are nine ground-floor rooms within the house.

When King Charles took over the management of the property, he oversaw changes including a revamp of its lavish interior and an overhaul of the grounds to make them more sustainable - including the installation of bird boxes.

Sandringham deviates slightly from other royal residences by also carrying a far cosier atmosphere, with plenty of home touches scattered among the ornate walls.

The King, a fan of gardening and the environment, also introduced around 500 rare breed cattle onto the estate and regularly uses their manure to serve as organic fertiliser to help the beautiful flowers.

The property also happens to be very close to Anmer Hall, a 10-bedroom house on the Sandringham Estate which was given to Prince William and Princess Kate as a wedding gift from the Queen in 2011.
