Beside his work in the palace construction, he was also given the court title of
hovjunkare and was attached to the court of Crown Prince
Adolf Fredrik and his consort
Louisa Ulrika, the sister of
Frederick the Great. Adelcrantz would remain in the shadow of Hårleman for several years more, spending the 1740s as his assistant in the work on the
Royal Palace in Stockholm that had been under continuous construction since the old Castle burnt down in 1697. He won the trust of Hårleman who recommended Adelcrantz for a mission to Italy to recruit artists for the palace project, and secured the necessary funding for the journey, enabling Adelcrantz to leave in 1750, accompanied by the royal sculptor
Jacques Philippe Bouchardon (a brother of
Edmé Bouchardon). The stay in Italy was a failure as far as recruiting new artists went, as the ones he wanted turned out to be far to expensive, but gave a rich yield in the form of architectural notes, books and art objects. Adelcrantz was back in Stockholm in late summer 1751. When Hårleman suddenly died in 1753, he was succeeded as
överintendent (see below) by
Carl Johan Cronstedt, and Adelcrantz was given Cronstedt's position as
hovintendent. The office of
överintendent had been created for
Nicodemus Tessin the Younger at the start of the planning for the new royal palace in 1697, with statutes modelled on the French royal office of the
surintendant who was responsible for the royal building works, and extended during Colbert's time to heading the royal manufacture of tapestries and porcelain. In the absence of royal factories of the French type, the Swedish office may in actuality been more closely have resembled the subordinate office of the
premier architecte. The task of the office was later extended to all public building projects, including churches. At the end of 1753, Adelcrantz was again given a foreign mission, now to Paris. In accordance with his instructions, he sent home a large number of models and engravings to be used for interior details in the latest fashion. He also contracted
Pierre Hubert L'Archevêque as a successor to J. P. Bouchardon, who had died in December 1753. In Paris, Adelcrantz sat for the portrait by Alexander Roslin that he later bequested to the Swedish Academy of Arts. Adelcrantz and Roslin may already have met in Stockholm before the latter left for the continent, or in Italy a few years before, but the stay in Paris appears to have been the beginning of a long friendship and an extensive but now-lost correspondence. The diary that he is known to have kept during his journey was mentioned as sold at auction in 1831, but also appears to be lost. After his return, he worked on the furnishing of the Palace which was finished in November, when he was appointed a Knight of the
Order of the Polar Star. The same year also saw his election as a member of the
Royal Swedish Academy of Sciences. ==Överintendent==
