Thinnfeld Castle

The two-story building has a rectangular floor plan and is surrounded by a park. Four corner pavilions are attached to the main block, while the garden front is slightly recessed. The main wing has a high, hipped gable roof, while the corner pavilions have mansard roofs. Above the entrance gate is the coat of arms of the Thinnfeld family. The facade is structured by a continuous cornice between the two floors. A stucco-decorated ornamental window is set into the gable of the three-axis central risalit.

The entrance hall has flat vaulted ceilings and a wrought-iron railing in the staircase. Significant artists of Styrian Rococo contributed to the interior design of the castle. Heinrich Formentini created the stucco ceilings in 1764. The ceiling paintings and wall hangings are by Joseph Adam von Mölck. In the three-axis, centrally located garden hall, the depictions of Bacchus, Ceres, Venus, and Vulcan are by him. In the adjoining room, Apollo and Daphne are depicted in a fresco. Another room shows biblical scenes painted in 1766, with Jacob and Rebekah at the well depicted on the ceiling. The furnishings also include Rococo-style tiled stoves and several portraits of the former lords of the castle. The house chapel is located in one of the garden-side corner pavilions and is dedicated to the Holy Trinity. The crucifixion group, consisting of a white-painted wooden crucifix and two adoring angels, was carved in 1768 by the South Tyrolean sculptor Veit Königer.
