King Charles III will go for a short vacation in his old residence in his Transylvanian property to rest after a busy Coronation week.
It added that Queen Camilla will not accompany the king, and will stay in her house in Wiltshire.
The Coronation Glove, worn to hold the sceptre, the sword belt, and the Stole Royal, will also be exhibited.
Camilla's dress with floral designs will also be in the exhibition.
Royal Collection Trust’s Sally Goodsir, the organizer of the special display, said: "We are delighted that visitors to the Summer Opening of Buckingham Palace will have the opportunity to view up close the ensembles worn by Their Majesties for key moments at the Coronation."
Goodsir added: "We hope that visitors will enjoy learning about the incredible craftsmanship involved and discovering the history and personal associations behind Their Majesties’ Coronation ensembles."
The Coronation display will be part of the Summer Opening of the State Rooms at Buckingham Palace, from 14 July – 24 September 2023.
