Our Friends at Wikipedia have the answer:
"A nativity scene may be used to describe any depiction of the Nativity of Jesus in art, but in the sense covered here, also called a crib or manger in the UK and crèche in France (meaning "crib" or "manger" in French), it means a three-dimensional commercial or folk art depiction of the birth or birthplace of Jesus, either sculpted or using two-dimensional (cut-out) figures arranged in a three-dimensional setting.
Christian nativity scenes, in two dimensions (drawings, paintings, icons, etc.) or three (sculpture or other three-dimensional crafts), usually show Jesus in a manger, Joseph and Mary in a barn, stable or cave intended to accommodate farm animals."Wikipedia: Nativity Scene
