The form of the stone, bell-shaped dome of the Frauenkirche is unique and is the largest building of its kind north of the Alps. However, it was the subject of repeated discussions both during and after its completion.

The original plans submitted for ratification by George Bähr in 1722 initially showed a copper-plated wooden dome, but this variant proved too expensive. Bähr thus suggested building the dome partly or completely of stone. The high load and questionable resistance to weathering of such a dome were, however, regarded as problematic. Expert opinions were commissioned and George Bähr questioned several times before a contract was concluded on the construction in stone in 1733.

The dome was finished in 1736, but cracks soon appeared in the inner piers and connecting arches. The City Council called for new expert opinions on its stability. These arrived at contradictory results: from a commendation of Bähr' work through to a call for the complete demolition of the dome.

In the end, the Council decided to leave the dome as it was and erect a lantern that was lighter than the one originally planned by Bähr. Unfortunately, Bähr did not live to see its completion; he died in 1738.
