Poset geometries are characterized as convex geometries verifying a given property. These geometries are basic structures in combinatorial nconvexity, because any convex geometry can be generated from them [3]. In this paper, we will give a necessary and sufficient condition on the closure operator which leads us to a new characterization of poset geometry.
