Redan (a French word for "projection", "salient") is a feature of fortifications. It is a work in a V-shaped salient angle towards an expected attack. It can be made from earthworks or other material.[1]

The redan developed from the lunette, originally a half-moon-shaped outwork; with shorter flanks it became a redan.
