In 1770, Charles Eugene established the Hohe Karlsschule on the grounds of Solitude Palace. It was at this school that Friedrich Schiller studied in his youth and wrote "The Robbers". The school moved into Stuttgart in 1775, the same year the Duke himself shifted his attention to nearby Hohenheim Palace in 1775. The last grand function held at Solitude took place in 1782, after which maintenance of the grounds ceased. From the 1830s, however, King Charles I renovated the palace, while Queen Olga met with her relatives in the palace.
