In 1970 a massive project crowdsourced thousands of photographs of everywhere in Paris (nearly every single grid square on each letter sized page, a rare few have no photos).

To see the photos, click on a map section to go to the subgrid page. Then find the square grid number that corresponds to where you want to see and click the corresponding numbered link from the list at the top.

Some cool example locations:
