Karneid Castle was probably constructed between the late 12th and early 13th centuries by vassals of the Prince-Bishopric of Brixen, an imperial estate of the Holy Roman Empire. The fortress stands perched dramatically on an inaccessible cliff face above the confluence of the Eggental and the Eisack rivers, on the historically resonant ancient border between the kingdoms of the Lombards and the Bavarii. The name 'Karneid' derives from the Latin 'cornus' meaning “horn”.
The courtyard with its fountain, the free-standing staircases and two-story loggia are especially worth noting for their picturesque quality.
Guided tours are available in the months of May, June, September and October.
