Not far from the geographic centre of Germany, in Niederdorla, lies the Germanic Opfermoor, or sacrificial marsh. The pre-Christian ritual site dates from the 6th century BC and is one of the best-preserved find complexes of its kind in central Europe.

In two archaeological excavation campaigns under the leadership of Prof. Behm-Blancke the ritual sites were excavated in the years 1957 – 1964 and a settlement extending over multiple periods from 1964 – 1976. The finds made during the course of these excavations point to intensive settlement in the region. An accurate reconstruction of a Germanic settlement and the exhibition pavilion with finds from the excavations are a popular excursion destination for families. At the site visitors can not only learn about everyday Germanic life on designated days, this is also possible for groups with prior notification.
