Stamp point 125 / Schalker Turm

The Schalke is a 762-meter-high mountain between Hahnenklee, Clausthal-Zellerfeld and Schulenberg.

The Schalk­er obser­va­tion tow­er was built in 1892 by the for­mer Harzk­lub Zweigvere­in Zeller­feld and restored in 1992 by the Harzk­lub Zweigvere­in Clausthal-Zeller­feld. It is about 10.5 meters high and weighs around 3.5 tons. 

From 1959, the Schalk­er lis­ten­ing post was also locat­ed on the sum­mit dur­ing the Cold War. This was a loca­tion for French air and telecom­mu­ni­ca­tions recon­nais­sance. In 1978/79, a 64 m high rein­forced con­crete tow­er was added to this lis­ten­ing post. Dur­ing this time, the Harzk­lub tow­er was moved 100 meters. 

After reuni­fi­ca­tion, the lis­ten­ing post tow­er stood emp­ty and was blown up in 2002. After the demo­li­tion, the Harzk­lub tow­er was moved back to its orig­i­nal location. 

From Fes­ten­burg, a hik­ing trail leads over the Lochstein HWN 126 at the Oberen Schalk­er Graben over 220 meters in alti­tude to the Schalk­er Turm. The short­est route leads from the “Auer­hahn” hik­ing park­ing lot to the sum­mit via the for­mer access road of the lis­ten­ing post.
