Kulpenberg, Mountain summit in Kyffhäuserland, Germany

Kulpenberg is a peak in the Kyffhäuser range in Thuringia that reaches about 474 meters in height. The mountain is surrounded by wooded landscape and accessed by several marked trails.

The mountain is part of the Kyffhäuser range, which has a long history of settlement and connection to medieval legends. The region became known through stories linking Emperor Frederick Barbarossa to the area in folklore and history.

The name Kulpe comes from a local word for a round, blunt end, describing the mountain's broad, rounded dome. The 3.7-metre sandstone column on the summit, inscribed "Königl. Preußische Landestriangulation 1879", was restored in 1999 by the Thuringian surveying office for the 120th anniversary of the Prussian triangulation.

The B 85 runs just north to east of the mountain, so the summit is usually approached on foot from the road or from Rathsfeld and the Rothenburg ruin. The rounded dome is only a little over 20 m high, and the 94 m TV tower stands near the restored 1879 sandstone column.

The 94-metre Kulpenberg TV tower, built between 1959 and 1964, stands beside a 3.7-metre sandstone column inscribed "Königl. Preußische Landestriangulation 1879". The column was restored in 1999 for the 120th anniversary of the Prussian survey. A large signal tower once stood next to it but was demolished before the TV tower was finished.
