Eiserner Mann

The Eiserner Mann stands 120 centimeters above ground as a cast iron pillar with a T-shaped base extending one meter into the soil.

First documented in 1625 as a border marker between Alfter and Heimerzheim, the pillar was relocated to its current position in 1727 by Prince Elector Clemens.

The iron pillar sparked discussions among researchers about medieval engineering capabilities and material science developments in historical Germany.

Located at an intersection of paths created in the early 18th century, the pillar serves as a meeting point for hikers exploring the nature park.

Metallurgical tests from the 1970s revealed the pillar was cast in an earth trench using medieval iron processing methods, displaying minimal rust despite its age.
