JuBla Turm Sirnach, Wooden observation tower in Sirnach, Switzerland.

The Hochwacht Sirnach is a 10-metre observation tower built in 2026 from hot-dip galvanised steel and wood. Its viewing platform sits 8.5 metres up, reached by 48 steps, and looks over Eschlikon, Sirnach and Wilen towards the Prealps and southern Thurgau.

The first Jubla tower, built of wood in 2010, stood 18 metres tall and was used for 15 years. Fungal infestation of the timber led to its demolition at the end of September 2023. The current Hochwacht Sirnach observation tower, 10 metres high, was erected in 2026.

The structure represented the commitment of Jungwacht Blauring organization to outdoor activities and environmental education for Swiss German-speaking youth groups.

The current tower, built in 2026, stands 10 metres tall and is reached by 48 steps leading to a platform at 8.5 metres. Parking spaces are located directly next to the tower. From the platform the view extends over Eschlikon, Sirnach and Wilen to the Prealps and southern Thurgau.

The current 10-metre steel-and-wood tower replaced the 18-metre wooden Jubla tower of 2010, which was demolished at the end of September 2023 after 15 years because of fungal infestation. The new structure was built in 2026.
