• ›A round hole in one chamber may have been used for alien astronomical observations

• ›Heinrich Himmler believed the site was the center of an ancient Aryan world — alien origins claimed by Nazi-era occultists

What Archaeology Says

The Externsteine are distinctive sandstone pillars in the Teutoburg Forest, used as a religious and possibly astronomical site from at least the early medieval period. A carved relief of the Descent from the Cross dates to c. 1115 AD. The solstice alignment of a round window is real but modest. The site's association with ancient Germanic religion is largely a 19th–20th century nationalist construction; evidence of prehistoric use is limited.
