The Ouvrage d'Eix was built between 1887 and 1888 and is located 600 m northwest of Fort Moulainville. The small infantry shelter was part of the Séré de Rivières system, a line of fortifications built from 1874 along the borders of France. The fortifications were named after their initiator, general and engineer Raymond Adolphe Séré de Rivières.

The Ouvrage d'Eix consists of a small barracks with three rooms, flanked by two small shelters. The work is surrounded by a rampart. The buildings are made of masonry and were not modernized after completion. It is therefore a fine example of 19th century French fortress architecture. Ouvrage d'Eix played no major role during the Battle of Verdun in World War I and survived the bombardments almost unscathed .
