Balmoral Castle, Scottish retreat of the Royal Family since the 1850s, is being opened up to the public for the first time in its history, Sky News reported.
From Monday, visitors can take a guided tour of a number of the Aberdeenshire castle's entrance hall, red corridor, main and family dining rooms, page's lobby, library and drawing room.
"The public who managed to get a ticket will come away [having seen] the Royal Family's holiday home. That's exactly what it is, it feels very homely," said James Hamilton Goddard, visitor enterprise manager for the Balmoral Estate.
The King is the latest in a long line of monarchs to add their own stamp to Balmoral since Queen Victoria and Prince Albert had the castle built in the 1850s.
"It's a magnificent place, I think the King wants people to see [it]," said Mr Hamilton Goddard.
