Tenebrae - Ciemna Jutrznia
On Wednesday, Thursday, and Friday of Holy Week in most Churches, including those in small villages, services are held in the early evening consisting of the chanting of "Ciemna Jutrznia" or Tenebrae, which is part of the Divine Office for the following day.
Following the services the children, in anticipation of Easter, play games, tricks, and practical jokes.  One common manifestation of this spirit is the lowering of the effigy of Judas from the Church belfry, attacking and beating it, and finally throwing it into a nearby creek or stream to drown.
