Jakobskreuz, Summit cross and observation tower on Buchensteinwand Mountain, Austria

The Jakobskreuz is a 29.7-metre steel lattice tower shaped like an upright double cross, built in 2014 on the Buchensteinwand at 1,451 metres. Inside, a left-turning staircase with 159 numbered steps winds around a central lift shaft, leading to four heated 33-square-metre viewing rooms at 18.5 metres and open platforms named Pillersee, Stoaberg, Großglockner and Kitzbüheler Horn.

The Jakobskreuz was built in 2014 by Bergbahn Pillersee on the initiative of three local founders, referencing the Jakobsweg pilgrimage route through the Pillerseetal. The steel lattice tower, 29.7 metres high, stands at 1,451 metres above sea level west of the Buchensteinwand summit. Since October 2020 the Antonius-Kapelle has occupied its base.

The name refers to the Jakobsweg (Way of St. James) running through the Pillerseetal; three local founders pushed the project for that reason. Since October 2020 the Antonius-Kapelle has occupied the tower's base. A summit book is kept in the head of the cross, above the four viewing platforms.

The Jakobskreuz stands at 1451 m, just west of the Buchensteinwand summit and slightly above the Alpengasthof Buchensteinwand, reachable by hiking trails or the Bergbahn Pillersee from the north. A lift runs from the ground floor to level 2 at 18.5 m; beyond that, 159 numbered steps lead to the top platform at 28.6 m. The four viewing rooms on level 2 are heated, and the upper platforms are open to the weather.

The four roof platforms at 21.4 m are named after the directions they face: Pillersee, Stoaberg, Großglockner and Kitzbüheler Horn. Each carries a telescope with the sighting targets labelled by name. A summit book sits in the head of the cross above the platforms.
