Franz-Josef-Warte, Observation tower in Hof am Leithaberge, Austria.

The Kaiser-Franz-Josef-Warte is an octagonal stone tower eight meters tall on the Steinerwegberg in the Leithagebirge, topped by a four-meter wooden pavilion. Its stone staircase runs up the outside to leave shelter rooms inside, and a wooden stair continues within the upper section. The tower overtops the surrounding forest, so the view from the top is unobstructed.

The Leithagebirge section of the Austrian Tourist Club, founded in 1885, erected the tower to mark 40 years of Emperor Franz Joseph I's reign. The foundation stone was laid on 18 August 1888, and the tower was ceremonially opened exactly one year later, on 18 August 1889.

Both variants of the name, Kaiser-Franz-Josef-Warte and Franz-Josef-Warte, are written on the building itself. The tower was erected by the Leithagebirge section of the Oesterreichischer Touristen-Club, founded in 1885, to mark 40 years of Emperor Franz Joseph I's reign. The section chose the finest viewpoint of the Leithagebirge for it.

External stone stairs lead upward to a platform where an internal wooden staircase continues the climb toward the viewing area. The ascent is straightforward and requires only basic fitness and balance.

The tower's name is written on the building in two forms, Kaiser-Franz-Josef-Warte and Franz-Josef-Warte, so visitors can spot both spellings on site. It stands on the Steinerwegberg, also called Kaisereiche, in the Leithagebirge near the Burgenland border.
