The Turgot Map of Paris was commissioned in 1734 by Michel-Étienne Turgot, and printed between 1734 and 1736.

The map is drawn from an isometric perspective and is in the form of 20 separate, non-overlapping engravings. The assembled map is approximately 2.5m high by 3.2m wide. The original copper plates are kept at the Chalcography of the Louvre, where they are still used to reprint copies of the map which are available for purchase.

The map can be found in a single file at Wikimedia Commons, and divided up into higher-resolution chunks at the Kyoto University Library and at Harvard University.
