Couples will be able to get married at Balmoral for the first time under plans proposed by the King to turn the estate into a wedding venue.
King Charles is hoping to convert the Queen's Building, which is metres from the castle, into a destination for "weddings, dinners, meetings and other events", according to The Times.
Unlike in England, wedding venues in Scotland do not need a licence, which is instead carried by the celebrant such as a registrar or priest.
A licensing application has been submitted to Aberdeenshire council for a "major variation" to the Queen's Building.
The proposals include changing the layout, increasing capacity and making use of an outdoor patio. The plans will increase the venue's capacity from 250 to 277 people inside and 40 to 144 outside.
According to the application, "the Queen's Building part of the premises may be used for weddings, dinners, meetings and associated events. These events may involve live performances and dancing where alcohol may be sold up to 12.30am". It added that events will be "rare throughout the year".
The estate argues there is no prospect of neighbours being disturbed by noise. Music outdoors will be kept at a "low level" through three small speakers, it claims.
Queen Victoria bought the lease for the 50,000 acre estate in 1848 and by 1855 the castle - considered to be the favourite residence of Queen Elizabeth II - had been rebuilt.
The estate, situated on the banks of the River Dee in Aberdeenshire, the royal family's private Scottish residence for more than 170 years, has increasingly been opened up to the public.
The Queen's Building was built in the late 1980s as staff accommodation and break rooms, and is fitted with a canteen. Last year it was converted to offer more dining space for tourists.
The running costs of Balmoral are reportedly more than £4 million a year. Including wages spent on staff. It generates around £500,000 in ticket sales from its 75,000 visitors which offsets a proportion of these costs.
This summer "adults only" guided tours through the heart of the castle for £100 a ticket were offered, with an extra £50 for visitors who wanted to have afternoon tea. The tickets sold out in 24 hours.
Further dates for next month and December were announced this month, with a seven-course locally sourced meal, paired with wine, for £250 per person.
Queen Elizabeth died at Balmoral in 2022 and there were suggestions that the house had been earmarked as a place of remembrance for the public.
When visiting Balmoral the King prefers to stay at Birkhall, once the residence of the Queen Mother.
The King and Queen landed in Samoa yesterday for the second leg of their most significant overseas trip yet. After a six-day visit to Australia, Charles and Camilla flew to the Pacific island nation to attend the Commonwealth Heads of Government Meeting.
