The tower is constructed primarily from Swiss fir and spruce wood, emphasizing local forestry.
It replaced a previous 19th-century observation point that historically stood in the same vicinity.
The 179-step design was engineered to provide clear sightlines above the existing tree canopy on the Hofberg ridge.
The viewing platform offers a 360-degree panorama that, on clear days, extends as far as the Black Forest in Germany.
The structure is designed to sway slightly in high winds, a deliberate engineering choice to ensure the longevity of the wooden joints.
The Wiler Turm is a 37-meter-tall wooden observation tower situated on the Hofberg mountain near Wil, Switzerland. Originally constructed in 2006, the structure was built entirely from locally sourced wood to provide panoramic views of the surrounding Toggenburg, Säntis, and Bodensee regions. The tower features a spiral staircase with 179 steps leading to an elevated observation deck. Its base is located at an altitude of approximately 700 meters above sea level. The tower is managed by a dedicated association that maintains the surrounding infrastructure, including nearby fire pits and seating areas. It serves as a prominent landmark for hikers traversing the local trail network in the Canton of St. Gallen.
