In 1883, a 10-metre-high, wooden viewing tower was built on the summit of the Schläferskopf; it fell into disrepair and was demolished in 1900.

It was made from local rubble stone and basalt lava with a room for "refuge and refreshing".

It comes from Wiesbaden glassworker, Albert Zentner, who also made the windows in the churches of Medenbach and Otzberg.

52,000 euros of the cost was met by the two mobile phone operators that have transmission equipment on the tower.
