After walking along the treetop path with a length of 500 m (165 ft), visitors can use the spiral ramp to climb the tower. Once at the top, visitors can enjoy a unique view over the world cultural heritage site of Steigerwald.
Structure
The lookout tower has the shape of a truncated cone that opens outward as it increases in height. At the tower base, the outside diameter amounts to about 20 m (66 ft) and at the top, to about 32 m (105 ft). The main supporting elements form 12 curved glulam timber trusses which are rotationally symmetrically arranged in an angular difference of 30°.
The outer spiral structure, made of timber, is fixed by steel cantilever beams to the timber supports. At a height of about 12 m (39 ft) is a half-pace, which is supported on diagonal braces made of steel.
The viewing platform at the top consists of steel cantilever beams, protruding to the inside, and longitudinal glulam timber stringers lying in between, with planking.
The structure is stiffened by a circumferential web made of steel diagonals and ring structures.
