Finally managed to visit the Hermannsdenkmal in the Teutoburg Forest.
This commemorates the Varusschlacht (Battle of Teutoburg Forest) which took place 2000 years ago and was a significant defeat to the Roman Empire. Modern archeology tells us that the actual site of the battle was probably 100 km further north.
The 19th century inscription translates the latin Arminius to German Armin. While due to lack of other sources the original name of the prince of the Cherusks will remain a mystery, I prefer Armin over Hermann.
Close by are the Externsteine, which were apparently an occult ritual site. Not hard to imagine given their impressive size and odd shape.
