These two give you a tour of what's under the Lincoln Memorial all the while telling and showing you little facts that you probably didn't know.

One of the cooler things they show you in the video is the 1920's graffiti that was preserved and left up on one of the columns that are underneath the memorial.

Another neat thing that is shown are how they replaced some of the steps throughout the years, but they didn't tear down the old steps. They just placed the new steps on top of them.

I know these kinds of things aren't for everyone, but I love this kind of stuff. The YouTube channel takes you to a lot of cool places. So, if you enjoyed this video, be sure to check out the rest.
