Create Your Own Historical Maps with WhatWasThere

Google Street View is great for getting an instant look at what a specific location looks like now, but what if you wanted to see that same location 50 years ago, or 100? The new site WhatWasThere.com aims to help do just that by letting users upload a tagged photograph of any building from any era to match its current location. The result is a remarkable view of our constantly evolving built environment.

Type in a geographic location on the site's main page, and you're then led to a map of that location with a column of photos on the left side that have their year and building name or site description listed. After selecting a photo, you're given the option of viewing the photograph layered over the same location today, via Google Street View. Adjusting the fade option one direction or the other helps you see how much the site has or has not changed.
