Following Peter Phillips's wedding this weekend, guests will gather at Gatcombe Park for the reception, according to new reports.
The estate belongs to Princess Anne, who lives in the main house alongside her husband, Sir Timothy Laurence.
For the late Queen Elizabeth II's eldest grandchild, the venue carries deep personal meaning as the place where he spent his formative years.
According to Hello!, the wedding arrangements have been entrusted to Peregrine Armstrong Jones, founder of Bentleys Entertainment, whose connections to the Royal Family run deep.

His portfolio of royal events includes celebrations for Princess Anne and the 2011 nuptials of Zara Tindall to Mike Tindall.
Beyond Palace circles, his client list extends to A-list celebrities, with David and Victoria Beckham's wedding and Hugh Grant's marriage to Anna Elisabet Eberstein among his credits.

Mr Phillips and Harriet Sperling will exchange vows this Saturday at All Saints Church in Kemble, Cirencester, in what promises to be one of the most anticipated royal celebrations of the year.
The private ceremony on June 6 holds particular significance as the church sits near the bride's childhood home in Gloucestershire.
Several prominent royals will not be present when the couple tie the knot.

Prince Harry, Andrew Mountbatten-Windsor and Sarah Ferguson have all been excluded from the guest list.
A friend of the couple told Hello!: "When and whether Andrew Mountbatten Windsor and Sarah Ferguson had been invited, it was probably not deemed appropriate to invite them. It's Peter and Harriet's special day, and clearly their attendance would cause a distraction to the whole day."
Regarding the Duke of Sussex's absence, the source added: "Peter and Harry haven't spoken for several years and have simply lost touch, so he hasn't been invited."
Both Mr Phillips and Ms Sperling have been married before. The groom, now 48, was married to Autumn Kelly for 13 years until their divorce in 2021, and they share two daughters: Savannah, 15, and Isla, 14.
