Ouvrage Haut-Poirier is a lesser work of the Maginot Line. The ouvrage consists of one entry and three infantry blocks, and is located between the Saare valley and petit ouvrageWelschhof, facing Germany. It is the only ouvrage in the Fortified Sector of the Sarre, the remainder of the area being covered by smaller blockhouses and areas of inundation. It was assaulted by German forces during the Battle of France and was captured after a seven-hour bombardment. Haut-Poirier is abandoned, although one of its satellite casemates is maintained as a museum.
Design and construction
The site was surveyed by CORF, the Maginot Line's design and construction agency, and was approved for construction in November 1934. The petit ouvrage was to be expanded in a second phase to gros ouvrage status with separate personnel and munitions entrances, two 75mm gun turret blocks and a 75mm gun casemate block.
Description
Haut-Poirier comprises three infantry blocks and a small entry block. The blocks are linked by an underground gallery system containing baracks spaces, ammunition storage and utility services. The galleries are excavated at an average depth of up to. The provisional entry block is located a short distance behind the combat blocks, accessed by a large drain. The proposed new entrances would have been several hundred meters father back.
Block 1: Infantry block with two automatic rifle cloches, two mixed arms cloches, and one machine gun/anti-tank gun embrasure.
Block 2: Infantry block with one GFM cloche and one retractable mixed arms turret.
Block 3: Infantry block with two GFM cloches, one mixed arms cloche, one twin machine gun embrasure and two JM/AC 47 embrasures. The block was heavily damaged by German bombardment in 1940.
Haut-Poirier also has two false cloches.

Manning

History
On 15 June 1940 German forces broke through the Saar gap. The German 262nd Infantry Division approached Haut-Poirier from the rear on 21 June. The Germans opened fire with 150 mm artillery at 1500 hours, concentrating on Block 3. Without artillery support from a gros ouvrage,and with Blocks 1 and 2 were unable to intervene, their fire blocked by terrain, Haut-Poirier surrendered at 2200 hours. The casemates nearby surrendered at the same time. After the June 1940 armistice the Germans stripped Haut-Poirier of all equipment. The ouvrage was in poor condition after the war and was not chosen for renovation.
Current condition
Haut-Poirier is on private property and is sealed to access. The Casemate de Wittring is maintained as a museum and may be visited.
