Kronprinz-Rudolf-Warte Graz, Protected observation tower in Graz, Austria.

The Kronprinz-Rudolf-Warte is an 11-meter-high stone observation tower on the summit of the Buchkogel in Graz's Straßgang district. Its rubble-stone base has arched openings on three sides, and an iron spiral staircase leads to a circular viewing platform overlooking Eggenberg, Straßgang and Wetzelsdorf.

The original wooden lookout on the Buchkogel, built in 1840 under the Abbot of Admont Abbey, burned down in 1874. In 1879 the Styrian Mountain Association rebuilt it in stone and iron as the Kronprinz-Rudolf-Warte, named after Crown Prince Rudolf. The tower was ceremonially opened on 12 October 1879 and handed over to Admont Abbey, with a deed walled into the foundation.

The tower is named after Crown Prince Rudolf, son of Emperor Franz Joseph I of Austria. It stands as a landmark for mountain hikers in the region and draws visitors who appreciate its historical connection to the Habsburg era.

You can reach the tower by hiking trails or by car to the Orthacker restaurant parking area followed by a short walk uphill. The site is accessible year-round, though weather conditions on the mountain can change quickly.

An iron spiral staircase climbs to the top of the structure, where the circular platform opens up views of the districts of Eggenberg, Strassgang, and Wetzelsdorf. The perspective from above reveals how these neighborhoods sit in relation to the city's center and the surrounding hills.
