The cathedral was severely damaged in the 1880 Zagreb earthquake . The main nave collapsed and the tower was damaged beyond repair . The restoration of the cathedral in the Neo-Gothic style was led by Hermann Bollé , bringing the cathedral to its present form . As part of that restoration , two spires high were raised on the western side , both of which are now in the process of being restored as part of an extensive general restoration of the cathedral . The cathedral is depicted on the reverse of the Croatian 1000 kuna banknote issued in 1993
