In some German-speaking communities; particularly in Catholic regions of western and southern Germany, Switzerland, Austria, South Tyrol and Liechtenstein, as well as in other Catholic regions of Central Europe, the "Christkind" (literally "Christ child") brings the presents on the evening of December 24 (Holy Evening or Heiliger Abend). The Christkind is invisible; thus he is never seen by anyone. However, he rings a bell just before he leaves in order to let children know that the Christmas tree and the presents are ready.
