Prince Harry reportedly stayed at Frogmore Cottage for one of the last times during his unexpected trip to the UK.
The Duke of Sussex made a series of surprise appearances at the High Court in London last week to attend a hearing of his latest legal battle.
The trip to the UK was believed to be the first time Harry has been back in the UK since the late Queen's funeral in September.
It was also the first time back in his home country since the release of his controversial memoir Spare and since learning he and wife Meghan Markle would have to leave their UK home Frogmore Cottage on the Windsor estate.
The property was gifted to the Sussexes by the late Queen after their wedding in 2018 but last month it was revealed it was being taken off with them and Harry and Meghan confirmed they had been "asked to vacate" it.
And according to The Telegraph, Harry stayed at Frogmore last week before they must finally leave just after the Coronation.
The publication adds that Harry is likely to have used the visit to organise the couple's belongings that were still at the property so they could be shipped to their new home in California. It is believed Harry flew back there last Thursday night.
Frogmore Cottage was converted into one home for Harry and Meghan, having previously been five separate properties for staff working on the Windsor Estate.
The whole renovation cost £2.4million and the property is thought to have five bedrooms, a kitchen, a sitting room and a nursery first designed for Archie.
The Sussexes only lived in the cottage for six months before sensationally quitting as working royals and moving to California. They repaid the cost of the renovations.
It has been reported that the home has been offered to Prince Andrew, who currently resides at 30-room Royal Lodge, also in Windsor, with former wife Sarah Ferguson.
Meanwhile, Harry's surprise return to the UK came nearly three months after he laid bare his troubled relationship with his father King Charles and brother Prince William in his controversial autobiography Spare.
Harry is not believed to have met up with his father while in the UK - even though the King was informed of his visit - as he was "busy" last Monday and Tuesday.
It is still unclear if Harry and Meghan will attend the Coronation in less than five weeks - although it has been confirmed they have been invited.
