Fort de Villey-le-Sec, also known as Fort Trévise, is a fortification of the 19th century, built as part of the Séré de Rivières system of fortifications in Villey-le-Sec, France, one of the defenses of Toul. It is a unique example for its time of a defensive enclosure around a village. Conceived after the defeat of the Franco-Prussian War of 1870-71, the fort was located away from the main combat zone of World War I and has remained almost intact. The fort's preservation association has been at work since 1961 to restore and interpret the site.
