The study focuses on the Prague exile of the last crowned French king Charles X in 1832–1836. It notices the popularization reflection of the king’s stay, which originated in the Czech milieu from the end of the 19th century. It arises from the memoirs of Charles’s contemporaries (including members of his exile court and Josef Rudolph of Wartburg, son of the inspector of Prague Castle, etc.), from reports of the Prague Police Directorate, a collection of reports submitted to Chancellor Metternich, from materials on the accommodation and furnishings options of Prague Castle and from the related results of art-historical research of the New Palace of the castle, where the king stayed with his family and a small court. It deals with the king’s interaction with the milieu of the Czech lands. Last but not least, it then deals with the upbringing of Charles’s grandson Henry, in which František Palacký and Joachime Barrande, among others, participated.
