DescriptionMetz en 1764 - Cours d'architecture Blondel Jacques-François.jpg
Français : Jacques-François Blondel - Cours d'architecture, ou Traité de la décoration, distribution et construction des bâtiments contenant les leçons données en 1750 et les années suivantes - planches du tome 4, 1773, planche L : Plan par masse des nouveau bâtiments et des nouvelles communications faites à Metz depuis 1764 (partiel)
It was previously considered to be in the public domain because it is a scan (or similar) by the Bibliotheque Nationale de France, but not everything scanned by the BNF is automatically in the public domain.
It is possible that this file is in the public domain for other reasons, for example because it was published a long time ago (anything before ca. 1900 is most likely ok) or because its author / artist / photographer died over 70 years ago and it was published over 95 years ago. In such cases, a new rationale should be applied, and a different license tag (see Commons:Licensing and valid license tags at Commons:Copyright tags) should be used.
If the file is not found to be in the public domain, it might be nominated for deletion (NOT by any automatic process, but manually).
See below for the previous rationale (not applicable anymore).
