Near the important hillfort site of Otzenhausen, famous Iron Age site traditionally linked to a Celtic prince enemy to Caesar, the project for an Archaeological open-air museum was started in 2011 and opened in 2016.
The massive structure of the celtic ringwall and the archaeological research carried out in the surrounding area gave life to the sustainable tourism project of a re-construction both of portion of the wall, both of the celtic village. With the aid of many institutions, the project aims to build a centre of attraction conveniently placed near the hillfort and the Nonnweiler dike on a surface of 2,5 he. It should be completed in 2015. Local groups are involved in the re-construction.
