Himmelsleiter, Wooden observation platform in the Hochmoor Nature Park, Schrems, Austria

The Himmelsleiter is a viewing platform in the Hochmoor Nature Park in Schrems, Lower Austria. Its wood-and-steel structure consists of 58 pairs of spruce trunks, each 19.4 m long, between which a 108-step steel staircase with intermediate landings leads up to a 33 m long platform at a height of about 18.4 m. Steel tie rods and wooden pressure beams between the trunks, plus a steel substructure, give it stability.

The tower was completed in 2002, designed by Viennese architect Manfred Rapf. The construction company Graf-Holztechnik from Horn built the structure.

The Himmelsleiter won the Lower Austrian Timber Construction Prize (Niederösterreichischer Holzbaupreis) after its completion in 2002. The jury recognised the combination of 58 paired spruce trunks with a steel staircase and steel tension rods, a design by Viennese architect Manfred Rapf executed by Graf-Holztechnik of Horn.

Access to the tower is by way of a paved path available from April through October for visitors. Winter months from November through March bring closure of the site.

The 58 spruce trunks are paired, each 19.4 m long, and the steel staircase between them has 108 steps with several intermediate landings before the 33 m platform at about 18.4 m. Steel tie rods and wooden pressure beams brace the pairs.
