Aussichtsturm Petersboden, Wooden observation tower in Rorbas, Zürich, Switzerland

Aussichtsturm Petersboden is a wooden observation tower near Rorbas that climbs to roughly 25 meters with a viewing platform at the top. A staircase of 137 steps and one intermediate landing lead visitors to views across the surrounding countryside.

The tower was built in 1978 by builder Walter Egg-Gattiker as a commemoration of his construction company's centennial milestone. The structure became a public landmark in the region following its completion.

Three panoramic information boards at the viewing platform provide details about the surrounding landscape, including views of the Rhine River and the Alps.

The tower is only reachable on foot. From the parking area at the highest point of Alte Bütbergstrasse, on the border between Rorbas and Bülach, a well-built hiking trail with little elevation change leads to the Petersboden tower in about 15 minutes.

The tower was a gift from builder Walter Egg-Gattiker, who erected it in 1978 for his firm's 100th anniversary. A fire pit stands beside it, and the platform holds three panorama panels. Northward lie Buchberg and Teufen with the Rhine and Irchel behind; southward the Alpen farm and parts of Bülach appear, with the Alps on clear days.
