What is the name of the area in a Catholic church where all the prayer candles are lit?

Answer 1

Roman Catholic AnswerThere is nothing in Catholicism specifically called a "prayer candle". Candles are lit in many places in a Church, By or on the altar in the sanctuary during Mass or other services. A candle or oil lamp must always be burning before the Blessed Sacrament. Candles are often lit out of respect before pictures or statues. And finally you may be referring to "lighting a candle" when you say a prayer. These banks of votive candles may be anywhere in a church, usually in a convenient place to pray before an altar or statue.
