Compare with one of my favourite maps of all times, the Turgot Map of 1730s Paris. The full-res image is worth the giant download, it's a lot of fun to just pan around.

The publisher Blondel la Rougery made a modernized one, I had a poster version from a mid-nineties copy of the French GEO magazine, now misplaced. Sadly they went out of business shortly afterwards, and the map seems out of print.

Here is a 1953 version from the Rumsey collection:

Theres some similar data from Montreal. I once made a draggable map out of a bunch if 1947 aerials a long time ago, but the hosting/dns screwed up when i moved the domain. Oh well.

I wonder if it would be possible to generate street view like navigation of the world decades ago by geolocating photos. Could we reconstruct a 1920s city for example?
nmstoker•3w ago
In popular areas with lots of overlapping photos, something akin to that was possible with PhotoSynth where it joined together matching photos projected into an inferred 3D space. Sadly the service was discontinued a while back.

I was able to do some browsing down memory lane. The photos pre-date the Paris I knew, but not by much. Thanks for sharing.

I'm struck by how empty the streets are.

There's a pretty great article here in English, full of details about this collection of over 30k amateur photographs: Catherine E. Clark, "'C’était Paris en 1970': Amateur Photography, Urbanism and Photographic History"

https://journals.openedition.org/etudesphotographiques/3407

Oh, and the source code for this website is here:

Quick summary for those confused:

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:

By the Eiffel Tower: https://paris1970.jeantho.eu/carres/718.html

The Arc de Triomphe: https://paris1970.jeantho.eu/carres/427.html

Gare du Nord (urban area train station, less touristy): https://paris1970.jeantho.eu/carres/268.html

Random southern Paris neighborhood (many photos of streets, people, more suburban): https://paris1970.jeantho.eu/carres/1296.html

Random central Paris neighborhood (lots of photos, mainly of the urban architecture): https://paris1970.jeantho.eu/carres/507.html
