Engineers discovered the cracks during a day-long inspection of the interior of the monument, AP reports. A 4-inch crack was discovered during an inspection of the exterior by helicopter soon after the quake, which also damaged the National Cathedral. The 555 foot-tall monument—the world's tallest stone structure—will remain closed to visitors indefinitely while engineers figure out how badly it has been damaged. Visitors at the site yesterday said they were relieved the monument survived the quake. "People may say the monument is broken like our political system,” one visitor tells the New York Times. “But the fact is, it’s still standing and so are we." (More Washington Monument stories.)
