The Wiler Tower is a 37 m high wooden tower that was erected in 2006 on the partially wooded Hofberg (723 m above sea level, 1.5 km north of the city center) near Wil SG in the canton of St. Gallen . From a distance, only the upper part of the slim wooden construction with the viewing platform is visible.
construction
The tower was designed by Julius Natterer .
Stairs
Viewing platform
The floor plan of the tower consists of an equilateral triangle with a leg length of 12 m at the base. This tapers to a height of 17 m, and then reverts to its original size at a height of 34 m. The viewing platform at 34 m height with 3 panorama boards is roofed and accessible via 189 steps.
The traffic and wind loads are carried over three X-shaped supports. An X consists of two upper and two lower round timbers, which are rigidly connected to one another at the level of the intermediate platform. The loads from the roof are entered into the external supports by three W-shaped trusses .
The core of the tower consists of a double spiral staircase with two independent flights of stairs (stairs to the tower, stairs from the tower), each 2.50 m wide. There are intermediate landings after every 18 steps. The steps made of solid wood in the format 18 x 36 cm were lined up in the middle on a metal spindle and screwed.
Only wood from the surrounding forests was used for the construction . Most of the wood, namely the round logs made from Douglas fir and the steps made from silver fir , were felled, cut and naturally dried in spring 2005.
