Altberg, Mountain summit in Zürich, Switzerland

Altberg is a mountain summit situated between the Limmattal and Furttal valleys, reaching 631 meters in elevation with multiple hiking paths crossing its slopes. The hillsides offer open views across the Zurich region and remain accessible to walkers of different abilities.

The hill lay in the catchment area of the Alemannic settler Tano, whose village became Dänikon. Tano arrived late, when most southern slopes were already taken, so his people settled north of the Altberg, where meadow and arable land remained. Farmers there used the three-field system, and the land belonged largely to the monasteries of Einsiedeln and Wettingen and to the Barons of Regensberg.

The construction of observation towers on Altberg since the 19th century reflects the local population's interest in appreciating the regional landscape views.

The 30-metre Altberg observation tower on the ridge was inaugurated on 10 July 2010 and cost 660,000 Swiss francs; it stands where a four-storey viewing tower already existed in the late 19th century. The hill rises to 631 m between the Limmattal and Furttal, about 3.8 km from Buchs.
