Frogmore House is a rarely-seen royal mansion on the Windsor Estate in Berkshire - one that the late Queen Elizabeth II never lived in at any point before or during her 70-year reign.

It is a Grade I listed residence and a 16th Century building. George FitzRoy, Duke of Northumberland - who was the illegitimate son of King Charles II and Barbara Palmer, Duchess of Cleveland - became the home's first royal resident.

Much-loved by the Royal Family, Frogmore House was then home to a number of residents until 1792. It was then bought by King George III for his wife, Queen Charlotte.

The home's unique name comes from the huge number of frogs that live on the marshland around the grounds, as reported by the Mirror.

It is also known to be the home to the Royal Mausoleum where Queen Victoria and Prince Albert are buried.

In the present day, the stunning royal home is a public attraction for visitors to enjoy the perfect gardens and mesmerizing interiors.

Despite its frequent visitors, photography is banned inside the home. This is to ensure that the inside of the home is kept top secret.

The residence has also played host to important royal occasions over the years - such as the wedding reception of Peter Phillips and Autumn Kelly in 2008. Most recently, it was also the location of the Duke and Duchess of Sussex's wedding reception in 2018.

The Duke and Duchess of York - who later became King George VI and Queen Elizabeth - spent part of their honeymoon there in 1923.

Other royals buried in the grounds near the home include The Duke of Windsor - who was formally known as Edward VIII, The Duchess of Windsor, Princess Helena, Princess Victoria, Prince George Duke of Kent and Prince William of Gloucester.
