While the Washington Monument is closed for earthquake damage repairs over the next year, 488 lamps will restore the marble tower's glow each night on the National Mall. As the spectacular sight is being been constantly captured by EarthCam's webcams, the company has also created a striking time-lapse video of the lighting of 555-foot-high national landmark. The striking footage shows the scaffolding climbing the obelisk from top to bottom, erected by workers with a head for heights.
