Externsteine

The Externsteine are a striking sandstone rock formation in the Teutoburg Forest and as such an outstanding natural attraction in Germany. Archaeological finds from the Palaeolithic (around 10,000 BC) and Mesolithic, in particular flint tips and flakes, have been secured from the immediate vicinity of the rocks, but these can only prove that the people of that time visited the stone group and for what reasons , cannot be inferred from the relics. However, there is no reliable evidence from finds for human use in the Neolithic, Bronze and Iron Ages.
In the immediate vicinity of the stones there are still several ravines, including the Große Egge ravine, which are often incorrectly referred to as the remains of "Roman routes".
