The National Trust for Historic Preservation has recognized the Cathedral’s significance to American history—and its extensive preservation needs—by officially designating it a national treasure. In making the designation, the National Trust will offer a full range of consulting and technical expertise to inform and motivate the extensive work of restoration, deferred maintenance, and long-term planning ahead.

Preservation needs are currently estimated at $50 million dollars, including $20 million alone as a result of the 2011 earthquake.
