Church (building)
The chancel is the most holy part of the church, and this is why it is often separated from the nave by a screen which can be made of wood or stone, or occasionally iron. The congregation can see through the screen. On the top of the screen there may be a cross. This is called a rood (pronounce like “rude”) screen. Priests used to climb up a staircase to the top of the rood screen to read the epistle and the gospel. Sometimes people sang from there.
