In 1767 the western cross-tower was struck by lightning and its roof was destroyed.
In 1769 the engineer Franz Ignaz Michael Neumann designed a new multi-story roof for the tower.
All the towers in the western wing were roofed with this new Baroque stone design, although care was taken to preserve the previous styles as well.
The pinnacles of the pediments on the chapels were replaced with urn-like structures.
The famed weathervane, called the Domsgickel, was added at this time as well.

The inside of the cathedral was heavily whitewashed.
A statue of St. Martin and the Beggar was erected on the roof of the western chancel in 1769.
