smithsonian:

A lot has changed since 1887.

This before-and-after view of the National Mall shows how different the space looks from 1887, when the first photo was taken, to 2015. (Oh hi there, @nmaahc!)

The photographs are from Smithsonian Institution Archives, who’ve kept track of how we look (and much more) through the ages. See more then-and-now photos in their blog post
