On April 14, 2019, a small fire occurred in the crypt; except for smoke damage, the cathedral building was mostly unaffected. Many artworks stored in the crypt were reportedly damaged or destroyed in the fire. An initial cleaning removed smoke damage from the bottom 10 feet of the interior of the cathedral. A cleaning of the rest of the interior was also ongoing. Ennead Architects proposed erecting a copper dome above the crossing so that the crossing's tiles could be rehabilitated. The restoration of the dome was completed in 2022.
