Ulrichsberg, Mountain peak near Klagenfurt, Austria

Ulrichsberg is a mountain near Klagenfurt featuring multiple hiking trails that connect to the Zollfeld region between St. Veit and Klagenfurt. Forest roads provide various access points to the summit, with the main route starting from Pörtschach am Berg.

The mountain first appeared in 10th century documents from Emperor Otto II as 'mons carantanus' and later received a Gothic church dedicated to St. Ulrich. Archaeological evidence points to even older religious structures that reflect different periods of settlement and use.

The mountain is the second of the four peaks of the Vierbergelauf, a procession held each year around Easter. Since 1958 the Ulrichsberggemeinschaft has also held its annual meeting here, formerly on the first Sunday of October and now on the third Sunday of September. The three Ulrichsberg bells were consecrated in 1984.

The mountain is accessible on foot via multiple routes offering varying difficulty levels. Visitors should wear sturdy footwear and be prepared for changing ground conditions depending on the season.

The summit house whose foundations are still visible beside the path was long read as a 1st-century sanctuary of the goddess Isis-Noreia, but research now assigns it to Late Antiquity. The mountain's first written record is a 983 charter of Emperor Otto II naming it "mons carantanus".
