Building
A few years after the early Altenmünster Abbey was founded in 764, a new monastery complex was built on a neighboring glacial sand dune. Charlemagne, to whom the abbey had been transferred, elevated it to one of his most important imperial monasteries. Charles was personally present with his family and court at the consecration of the monastery church in 774. Three monastic buildings of the once large complex remain: a fragment of the Nazarius Basilica, a section of the monastery wall and the famous King’s Hall. In addition, there are the post-monastic buildings: the exhibition depot tithe barn, the electoral manor (now the administrative headquarters), the former forestry warden’s building and the so-called Adalherhaus, which is home to the museum’s education department.
