[Under development] Le Plan Scénographique de Lyon c. 1550 is a giant axonometric scenic map of the French city of Lyon created during the height of the French Renaissance. The complete map is 1.7 meters high by 2.2 meters wide and is composed from 25 copperplate-printed, laid-paper sheets, each 34x44cm on average. Probably the earliest detailed view of the city, "Le 1550 Plan Scéno" was produced approximately between 1544 (identified as the principal date of the survey drawings) and 1553 (after which date some built structures depicted in the map are known to have no longer existed).

The scale bar accurately shows the real-world measurements of the original and 1876 facsimilé (same size), but the other featured derivative maps are significantly smaller (and therefore display in lower detail). To view the original map at it's approximate real-world dimensions, set the zoom level to ~32%.
Note that the view may temporarily appear blurry as it waits for the high-resolution images to download (dependent on the server speed and your Internet connection). To accelerate the loading of the part of the map you are currently looking at, I have found that it helps to reload the page at its current view (the url address contains the current XYZ coordinates, so the map will not reset).
