The Municipality of Orbey, owner of the building of the Memorial Museum of the Linge (Battlefield of the Linge - 1915), wishes to create an extension of the said Museum (located on a protected land under the title of Historical Monuments). The objective of the operation is to: - Streamline visitor traffic (entry and exit direction); - Improve the comfort offered to volunteers providing reception and ticket sales services (space, protection against drafts, easy management of visitors); - Create a real shop (postcards, books, DVDs, targeted souvenirs) to improve the economy of the operation of the association which is not subsidized.
