In spring 1862, Sandringham House with its estate at the time of 2,800 hectares was bought from Cowper as a country home for Albert Edward, Prince of Wales, who had just turned 21.
Queen Victoria and Prince Albert had decided that he should move from the family home to a house of his own, as stated in historichouses.org.
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.
Once beloved by the late Queen Elizabeth, 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 Great Saloon was said to be a firm favourite of the late Queen who often relaxed there to complete jigsaw puzzles as reported in OK! Magazine.
The estate has a large White Drawing Room which has often welcomed foreign guests over the years, with ornately carved walls and ceilings with gold-finished furnishings.
The room also boasts a beautiful portrait of Queen Alexandra, the wife of King Edward VII, which hangs over the fireplace.
Another key room to the property is the green dining room which holds the Royal Family Christmas dinners.
The King 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.
