King Charles and queen camilla reveal Balmoral Castle to the public for the first time amid cancer battle.

King Charles III is making a royal move that’s never done before: opening the doors to Balmoral Castle.

For the first time since the Aberdeenshire, Scotland, castle was completed in 1855, guests will be granted behind-the-scenes access to the landmark. Queen Elizabeth II, the United Kingdom’s longest reigning monarch, died at the private estate at the age of 96 in September 2022; the residence was where the queen and her family would spend summer holidays.

Tickets for the historic event – with tours scheduled between June 1 and Aug. 4 – sold out this week within a day of being released, according to the BBC.

According to its official website, Balmore is the Scottish castle that serves as a beloved home for the royal family, which was purchased for Queen Victoria by Prince Albert in 1852

Historic opening of royal residences to the public comes amid royals’ health battles

The monarch’s unprecedented decision to open up royal residences comes amid changes within the monarchy.

The East Wing of Buckingham Palace is set to open to the public for the first time this summer, like Balmoral Castle. Guided tours of the palace’s principal floor are scheduled from July through August, per the BBC.

The guided tours also come as seniors members of the royal family are battling health issues. After Catherine, the Princess of Wales, was notably out of the public eye for several months, Kensington Palace shared a video of Princess Kate in which she revealed she had been diagnosed with cancer.
