Aufi Tower, Police radio tower in Aufhausen, Geislingen an der Steige, Germany

The Aufi Tower is a concrete transmission tower in Aufhausen near Geislingen an der Steige that serves police radio and telecommunications purposes. The structure rises to about 132 meters in height and impresses with its slender form, measuring only about 6 meters in diameter.

The tower was built in 1965 as a police radio tower for Aufhausen, a district of Geislingen an der Steige. In the 1960s and 1970s repeated static measurements were carried out on the structure, which is not open to the public. Private providers now also use it for telephony and internet.

Locals call the tower "Aufi", a short form of Aufhausen, the Geislingen district where it stands at 786 metres on the northern edge of the Swabian Alb. Besides the police, private providers use it for telephony and internet, so the mast carries civilian traffic as well as police radio.

The tower can be viewed from the outside and offers a distinctive landmark with its recognizable form in the landscape. Interior access is not possible since the facility operates as a technical installation not open to visitors.

At 132 metres tall with a diameter of only 6 metres, the Aufi is described as the slimmest modern reinforced-concrete radio tower ever built. Its height-to-diameter ratio of 22 to 1 drew repeated static measurements on the structure in the 1960s and 1970s, even though the tower itself was never open to the public.
