Lucky visitors will get to walk in royal footprints as they can tour Buckingham Palace's iconic East Wing for the first time.
But one area will still remain firmly out of bounds - the iconic balcony.
The Sun got a glimpse inside the summer's hottest tourist attraction after King Charles decided to open up the palace to make it more inclusive.
The wing has undergone a 5-year renovation with every floorboard ripped up, everything rewired and 3,500 works of art removed and restored before being put back in place.
The 45-minute tour includes the Yellow Drawing Room where the late Queen would sit for portrait paintings.
It gives access to the 240ft long Principal Corridor with Japanese, Chinese, English and French artwork - and the Centre Room where royals pause before emerging to greet The Mall.
More than 6,000 tickets have sold out to the first tourists to pause before the famous balcony where Royals emerge for events like Trooping the Colour and King's Coronation.
