During the erection of St. Paulus Dom, most of the preceding (Ottonian) cathedral was demolished with only masonry fragments being retained (apparently in the west transept and the southern side-aisle).
The Westwerk erected in 1192 (the Old Choir and the two west towers) was incorporated into the current structure.

From the perspective of architectural history, the modern cathedral is divided into two parts: the Romanesque westwerk and the Gothic building.
