Dom Sankt Peter
Charlemagne founded the diocese of Osnabrück. Today's late-romanesque cathedral was erected from 1218 to 1277 and consecrated 1277. The shape is dominated by the two Western spires, which were built with 400 years in between. The triumph cross in the church was manufactured in the 12th century and is the largest cross in Lower Saxony.
