We don't have an iconostasis, if that is what you mean. We just have a raised altar area (bema) with a curtain that is drawn during certain times. It's my understanding that this is more ancient.
Or did you really mean iconoclast? We are not iconoclasts. We use icons in the church, although you won't usually see as many icons in an Armenian Church as you do in a Coptic or EO church.
The icon above the altar is supposed to represent the Incarnation. It is supposed to be of St. Mary holding the Christ Child. I've heard it referred to as "the icon of our Salvation," because it shows Christ coming into the world to save us.
