In 1081, fire once again struck the cathedral, and the appearance of the Salian western end is not known. In 1100, Henry IV ordered reconstruction in the old Lombardic style. The old flat chancel end on the east side was replaced with a large apse, which external gallery with a narrow arcade supported by short columns crowned the semicircular wall with a wide pseudo arcade and tall pillasters on both sides. The new chancel had a triple-nave crypt. The damaged square tower had been replaced with an octagonal dome, above which an octagonal tower was added later. Flanking stair turrets remained from the first cathedral. These changes closely resembled the renovations Henry had overseen on Speyer Cathedral a few years earlier.
