In February 2011 , the Los Angeles County Museum of Art received a grant from the James Irvine Foundation to scientifically assess and report on the condition of the Watts Towers , to continue to preserve the undisturbed structural integrity and composition of the aging works of art . Weather and moisture caused pieces of tile and glass to become loose on the towers , which are conserved for reattachment in the ongoing restoration work . The structures suffered little from the 1994 Northridge earthquake in the region , with only a few pieces shaken loose . An extensive three-year restoration project by the Los Angeles County Museum of Art began in 2017 and suspends public tours within the site ( tours outside of the fenced towers and sculptures are still available )
