Alteburg Tower

Suddenly a tower in the middle of the forest ... many hikers around it (Soonwaldsteig) who tell the mountain biker who is not tower-savvy that the view is beautiful :-)

Very nice observation tower, but it is relatively well attended. For mountain bikers, the trail up or back down is more of a highlight :)
The tower briefly in the video at 9:48-10:25

"The 20 m high Alteburg Tower has stood on the Alteburg summit since 1893. It was built as an observation tower by the then Soonwald Club; today it is owned by the Hunsrück Association. It is a listed monument[3] and is freely accessible. Two staircases on the outside of the tower lead to the high entrance opposite, followed by a spiral staircase with 67 steps up to the covered observation platform."
