Washington National Cathedral built of Indiana (Bedford) limestone and 2011 earthquake damage

Washington National Cathedral was constructed primarily of Indiana limestone quarried in Bedford, Indiana, with much carving performed by stonecutters over the building campaign from 1907 to 1990. The cathedral suffered damage to limestone pinnacles and other stone elements during the August 23, 2011 earthquake, prompting documented restoration and stone-repair work. Conservation reports and news accounts record both the building's Bedford limestone construction and the post-earthquake stone restoration efforts.
