DESCRIPTION: Antique chart of the west coast of France from the Anse de Cornaud and Pointe du Grand Mont southward to le Croisic. First published in 1826, this chart of Brittany includes part of the Department of Morbihan, and the mouths of the Penerf and Vilaine rivers. The chart is updated as of 1907. Settlements and habitations covered include Cornaud, Saint-Gildas-de-Rhuys, Chateau de Suscino (en ruins), Damgan, Port de Billiers, Penestin (Pennetin), Mesquer, Piriac-sur-Mer, la Turballe, Guerande, Clie, and Saille. The chart extends westward to include the Ile d'Hoedic and many surrounding smaller islets of the greater and lesser Cardinaux Islands.
Very extensive and minute detail of the shoreline and near shore areas with elevation denoted by fine hachuring. Hundreds of individual structures are placed accurately. Thousands of soundings with isobath contour lines and navigational hazards would have aided the coastal navigator in the area.
This is a early 20th century linen-mounted folding chart, an updated edition of a chart first published by France's Depot de la Marine in 1826. This sea chart is based on the original surveys conducted in 1820 and 1821 under the supervision of Charles-François Beautemps-Beaupré (1766-1854), considered to be the father of modern French hydrography. Linen verso is printed via letterpress with "De La Pointe du Grand-Mont AU CROISIC. Entrée de la Vilaine."The Depot de la Marine was established in 1720 under the French Ministry of the Navy to collect, preserve, and publish nautical charts, sailing directions, and maritime intelligence for the French naval service. Its purpose was both archival and practical: to centralize geographic knowledge gathered from voyages, surveys, and colonial administration, and to convert that information into standardized charts for navigation. Over the eighteenth century the Depot became the principal hydrographic authority of France, issuing engraved sea charts that incorporated data from naval expeditions, colonial outposts, and scientific voyages.
Following the French Revolution, the institution was reorganized and its chart production expanded, particularly during the late eighteenth and early nineteenth centuries as global maritime competition intensified. The Depot de la Marine supervised official surveys, revised earlier charts, and maintained copperplates for continued reissue as coastal knowledge improved. In 1886 it was formally reorganized as the Service hydrographique de la Marine, the predecessor of today’s French hydrographic office. Charts bearing the Depot imprint remain important records of French naval activity, colonial expansion, and the technical development of European hydrography.
