De hoofdmuur (noordwal)

Constructed in order to block off the populated mountain crest from the remaining flat mountain ridge, the main wall for defence reasons had to be considerably stronger than the side walls. The north wall was stronger than any other fortification wall of the day. At over 10 m high and 40m thick, the wall remains we can still see today give an imposing impression of what it must have been like. At the time of its greatest extension, the wall was around 20m high and equally as thick. This corresponds to around the height of a five-storey building…

The typical construction method for Celtic fortification walls was described by Caesar as "murus gallicus" (Latin = Gallic wall). Excavations confirm that the enclosure wall of Otzenhausen was also constructed according to this principle. It is based on a wooden and nailed-together framework of logs, with the inner cavities being filled with earth and stones. The outer facade of the wall was covered with a dry stonework. The present-day talus cone is the result of several construction phases, about whose age and appearance little is known. It can be presumed that the defence walls and hence the entire site date back to the early Latène period (5th-4th century B.C.).

The "Hunnenring" was probably most recently abandoned without a struggle in the middle of the 1st century B.C. during or just before the Roman occupation.

The warring methods of the Celts: attacking enemies were kept at bay with spears, arrows and bows as well as catapults. Lance, dagger and sword were used for hand-to-hand combat. Shields offered additional protection.
