Uhlberg, Mountain summit in Filderstadt, Germany

The Uhlberg is a 469.8 m high elevation of the Schönbuch in the Esslingen district, rising south of the Filderstadt districts Plattenhardt and Bonlanden. On its southern summit clearing stands the 25 m high Uhlbergturm, a concrete observation tower built in 1963, with a covered viewing platform.

A wooden viewing frame was erected on the summit in 1890 and replaced in 1903 by a 17.5-metre wooden tower, which had to be demolished in 1961 due to pest infestation. The present 25-metre concrete tower, built by the Gustav Epple company to plans by architect Karl Hörz, dates from 1963. During the Second World War the tower was used by the military to spot enemy aircraft early and sound the alarm for Stuttgart.

The Uhlbergturm is run by the Schwäbische Albverein, a Swabian hiking association that keeps a small kiosk with a common room attached to the tower. The kiosk opens only at weekends and on public holidays, and a barbecue area beside it is not open to the public. The tower itself is open on the same days.

The observation platform is open to the public at certain times for visitors who wish to climb to the top. Clear weather provides the best conditions for a visit and enjoying the views.

During the Second World War the tower was used by the military: enemy aircraft could be spotted from here early and an alarm passed on to Stuttgart in time. Since 2009 a digital authorities' radio antenna has stood on its roof.
