Schloss Solitude was built as a hunting lodge between 1764 and 1769 under Duke Karl Eugen of Württemberg. Schloss Solitude was originally designed to act as a refugium, a place of quiet, reflection and solitude (thus the name). Construction of the castle was plagued by political and financial difficulties. Karl Eugen had taken Württemberg into the Seven Years' War on the losing side against Prussia. The building exceeded the budget allocated by the duchy of Württemberg. Further, political wrangling between the duke and influential Stuttgart land barons led to the duke moving temporarily from Stuttgart to Ludwigsburg. In the long run, the castle was prohibitively expensive to keep just as a temporary residence. In 1770 it housed a high school founded by Duke Eugen. In 1775, the Karlsschule academy moved to Castle Solitude. It served as an academy of arts, a military academy, and later a general university for children of the elite. Eventually, maintenance costs led to its closure as a school after the Duke's death late in the 18th century. Between 1972 and 1983, the Federal Republic of Germany restored the castle.
Since 1990, the annexed buildings (Officen-building and Kavaliers-building) have housed the Akademie Schloss Solitude. The Kavaliers building incorporates living quarters for students.
Castle Solitude was designed by a working group at the ducal court under the guidance of Philippe de La Guêpière with active input from Duke Karl Eugen and master craftsmen. Its exterior is typical Rococo. On the inside, however, the style is characteristic of classicism: instead of the irregular lively forms typical of Rococo, the proportions of the rooms and wall are typically classical in design.

The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
