The history of the Castle in Otmuchów dates back to the 12th century, when Pope Hadrian gave authority to the land to the Bishop of Wrocław, including the castle. Throughout the next centuries the castle gained its significance, when Bishop Preczlaw of Pogarell called Otmuchów the capital of the Duchy of Bishops. The castle changed its architectural style to that of the Renaissance during reconstruction work in the seventeenth century. In 1810 the partially devastated south-eastern wing of the residence was deconstructed. Currently two wings of the castle survive, both having four levels.
After the secularisation in 1810, the castle was left in ruins, while the lands were given off to the powerful House of Humboldt; the Duke of Humboldt used the material from the former, other two wings to repair the currently standing reconstructed wings. In the location of the former wings, the owner built a small castle-garden, while his brother Alexander von Humboldt sent in exotic trees, such as the smoketree, ginkgo, or the Canadian lime tree.
One of the most unusual parts of the residence's interior is located in the castle's two small cells of death, where prisoners were told to enter, and fall down a 20-metre drop, where there is a scripture Go you are free (Idź jesteś wolny); the sudden drop let to the stone courtyard with a sharpened birch perch.

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.
