St Michael's Church was built between 1010 and 1020 on a symmetrical plan with two apses that was characteristic of Ottonian Romanesque art in Old Saxony. Its interior, in particular the wooden ceiling and painted stucco-work, its famous bronze doors and the Bernward bronze column, are – together with the treasures of St Mary's Cathedral – of exceptional interest as examples of the Romanesque churches of the Holy Roman Empire.
