Zeller Berg, Alpine summit in Tyrol, Austria

Zeller Berg is a 597 meter (1,959 foot) Alpine summit in Tyrol with gently sloping sides covered in typical mountain vegetation. Several marked trails cross its terrain, connecting different starting points to the top.

In the Middle Ages there were plans to build a second fortress on the rock opposite Kufstein Fortress, but they were never carried out; only a small defensive structure was built and long since removed. A retired non-commissioned officer noticed terraces while surveying the hill for a cross-country run, and old war-archive maps in Vienna led the University of Innsbruck to excavate from 2019 to 2021, uncovering building phases back to Emperor Maximilian's time, including a gilded belt buckle and a late-Gothic green-glazed stove tile. In 1805 Bavarian troops took the site without a fight, and it was demolished in the 19th century.

The mountain lies in the Zell district and was only incorporated into Kufstein in July 1947, having belonged to the neighbouring village of Langkampfen before; Kufstein gave the Pfrillsee area to Langkampfen in exchange. Because of this, Morsbach, whose Kufstein cadastral district includes the Zellerberg, today lies in both municipalities. A sporting forest mile runs on the mountain.

The mountain rises about 100 metres above the valley floor in the Zell district, separated from the Inn only by the railway line. A steep slope runs directly beside the ÖBB track, so the line is repeatedly protected against rock and tree falls. A sporting forest mile (Forstmeile) runs along the Zellerberg.

A retired non-commissioned officer noticed oddly level terraces on the slope while surveying the hill for a cross-country run; old war-archive maps in Vienna led him to push Innsbruck University's archaeology institute to dig. Excavations from 2019 to 2021 uncovered a multi-phase fortification reaching back to Emperor Maximilian's time, including a gilded belt buckle and a late-Gothic green-glazed stove tile.
