If you're afraid of heights you probably won't want to click play on this video. However, if you've always been interested in what exactly Washington DC looks like from the top of the Washington monument then this is your lucky day.
One of the brave souls currently working to repair the monument after it was damaged in a 2011 earthquake strapped a video camera to his helmet and took some footage.
The resulting video is both spectacular and terrifying.
