Charles and Camilla will unveil the staging for the Eurovision Song Contest and tour arena on Wednesday.
The King and Queen Consort will have a tour around the M&S Bank Arena and meet UK contestant, Mae Muller, alongside celebrity presenters and creative teams, ahead to the iconic contest in May.
The grand final of the competition will take place on May 13, just one week after the King's coronation.
Eurovision 2023 will take place in Liverpool, on behalf of War-torn Ukraine.
It will be the first time the competition has been held in the UK for 25 years.
On Wednesday, Charles and Camilla will be met at the arena by BBC director General Tim Davie, BBC director of Content Charlotte Moore and managing director for BBC Eurovision 2023 Martin Green.
They will meet representatives from the BBC Board, BBC Studios and the managing director of the arena Faye Dyer.
The royal couple will be given a backstage tour and meet production staff before being invited to light and animate the arena, revealing the staging for the first time.
The couple will also be introduced to Eurovision hosts Julia Sanina, Hannah Waddingham, Scott Mills and Rylan Clark, before meeting with this year’s UK entrant, Mae Muller, alongside Blue Peter presenters.
Charles and Camilla’s visit to the arena is one of several royal engagements in Liverpool, recognising the cultural partnership of the UK and Ukraine and celebrating Eurovision.
Touring the library space, Charles will meet Ukrainian refugees and their host families who have been supported by The Prince’s Trust while Camilla meets young people as part of a story telling session.
The pair will then together meet members of the Ukrainian Community in Liverpool and their host families.
Charles will later reveal a plaque to mark the twinning of the libraries, during a live link with the site in Odesa, and the visit will end with a performance by English National Opera.
