The monument shut down Aug. 23, 2011 after a 5.8-magnitude earthquake rumbled through the East Coast. Workers discovered dislodged stones and mortar, along with cracks, following the quake.
The iconic 555-foot obelisk sported a new look for many months: It was surrounded by scaffolding as workers made the repairs. Following the quake, Washington philanthropist David Rubenstein pledged to pay half the $15 million repair bill. Congress allocated funds to pay the rest.
