Hagenturm, Steel observation tower in Merishausen, Switzerland

Hagenturm is a steel observation tower located in Merishausen, Switzerland, standing 40 meters tall with a lattice frame structure. From the top, visitors can see across the rolling hills and valleys of northeastern Switzerland.

Engineer Erwin Klaiber designed and built the tower in 1989, completing it within three weeks. It replaced an earlier surveying structure that once stood at the same location.

The tower's name comes from the Hage, the 912-metre summit of Canton Schaffhausen just 93 metres to the north. Four panorama panels on the platform identify the view, which reaches from the Black Forest to the Alps. A webcam on the tower shows the current view in real time.

Access to the viewing platform is via 225 steps, not a spiral staircase. The platform has seats and four panorama panels; above the treetops the view runs from the Black Forest to the Alps. The tower stands at 908.5 m above sea level, 93 m south of the Hage, the highest point of Canton Schaffhausen at 912 m.

The tower carries a radome of the Swiss Army on its top, and the 2,300 m² plot with its access path belongs to the Confederation. The old 1903 tower, 14 metres of reinforced concrete, had its lowest ladder section removed in 1949 and stored at the Beggingen customs office.
