Cholfirst Radio Tower, Communication tower in Flurlingen, Switzerland

The Cholfirst Radio Tower is a 96-metre free-standing steel lattice tower on the 570-metre Cholfirst mountain near Flurlingen, south of Schaffhausen. Built in 1973, it has a triangular lattice framework and an observation deck at 42 metres, reached by a spiral staircase of 191 steps fixed to the outside of the tower core.

The tower was built in 1973 by PTT, the Swiss postal and telecommunications service, after an experimental television transmitter on channel 47 had operated for three years on a 40-metre tower nearby. Construction cost 7 million Swiss francs. At the request of the Flurlingen community, an observation deck was added at 42 metres, with PTT covering the extra cost.

The tower is named after the Cholfirst hill, and its viewing platform was added at the request of the Flurlingen community, which asked for public access. From the deck, visitors look northwest to Neuhausen am Rheinfall, north over Schaffhausen and Feuerthalen, northeast to the German exclave of Büsingen, and south across the Alps.

The observation deck at 42 metres is reached by a spiral staircase fixed to the outside of the tower core, 191 steps in all; there is no lift. The platform was added at the request of the Flurlingen community, with the extra cost covered by the PTT. To the northwest you can pick out Neuhausen am Rheinfall, to the north much of Schaffhausen and Feuerthalen, to the northeast the German exclave of Büsingen am Hochrhein, and to the south the whole Alpine panorama.

The tower's observation deck exists because the Flurlingen community asked for it during planning; the extra cost was covered by PTT. The platform sits at 42 metres and is reached by a spiral staircase fixed to the outside of the tower shaft, 191 steps in all.
