Adendorf Castle is a two-part complex consisting of a castellated mansion and a forecourt south-east of it, which stand on a common island with a rectangular shape.
The wide moat surrounding the island is framed by a wall and pond-like around the mansion. It is fed by the mill creek. In addition to extensive forest and agricultural areas, the estate includes a landscaped castle park with mature trees. The remains of a formal garden, which can still be recognized in its basic concept, are integrated into it. It is located outside the moat north of the castle building.
The eight-axle main facade of the building is located on the southeast side and points to the outer bailey. In its fifth axis, the rusticated portal is a bit lower than the ground floor. A double-flighted staircase with a curved shape leads up to it. It is crowned by a flat triangular gable whose gable triangle shows the coat of arms of the von der Leyen family. Behind the portal is a gatehouse with two groined vaults separated by arches.
In addition to a wooden staircase from the late Middle Ages in the great hall, a Renaissance chimney with numerous coats of arms can be found on valuable interior fittings. He came to Adendorf around 1900 from Konradsheim Castle, which was also owned by the von Loë family, and displays the coats of arms of the following noble families: Waldbott, Schall, Bernsau, Haeß, Wachtendonk, Loë, Schinck and Nesselrode.
