Frogmore Cottage is the only royal residence Queen Elizabeth has never stayed at.
The Queen
According to HELLO!, the British monarch has never actually spent the night at Frogmore which is located on the grounds of Home Park in Windsor, England.
The Duke and Duchess of Sussex were given the property as a wedding gift from the queen to be their home, and the couple spent at least £2.4 million ($3.05 million) of taxpayers' money renovating the property before leaving their positions as senior members of the British royal family and relocating to California. That sum has now been paid back by Prince Harry.
The Duke and Duchess of York’s daughter, Princess Eugenie - who is Harry’s cousin - currently lives there with her husband Jack Brooksbank and their son August, who was born in February 2021.
However, it has been stated by royal biographer Omid Scobie that the house is only “on loan” to the couple.
Posting on Twitter, he said: "Frogmore Cottage continues to be the couple's residence in the UK and they are delighted to be able to open up their home to Princess Eugenie and Jack as they start their own family. They have not moved out and will still stay at the house during UK visits."
The house - which gets its name from the abundance of frogs that inhabit the marshland around the grounds - has hosted many royal events over the years and is also home to the royal Mausoleum where Queen Victoria and Prince Albert are buried.
As well as hosting Harry and Duchess Meghan’s wedding reception it was also the venue where the reception of the Princess Royal’s son, Peter Phillips and his wife Autumn Kelly, took place.
Frogmore House will be re-opened to the public in 2022 as a visitor attraction, although the inside of property will not be accessible due to the precious art and antiques within.
