Reenactors portraying first US President George Washington and his wife Martha, look on May 12, 2014 during re-opening ceremonies at the Washington Monument in Washington, DC. The Washington Monument, one of the US capital's most recognizable sights, is set to re-open Monday, three years after sustaining damage from a rare earthquake.The popular tourist attraction is the US capital city's tallest building at 555 feet (170-meters). The obelisk, built in honor of the first US president, George Washington, was closed after engineers found 150 cracks in the structure following a 5.8-magnitude earthquake in the neighboring state of Virginia in August 2011.
