This is a typical Iconostasis found in Greek Orthodox Churches. Note the blue curtain that covers the "Great Doors." These are opened during part of the Eucharist portion of the service. Behind the Iconostasis is the altar where the elements of the Eucharist are consecrated.
To the left of the "Great Door" (as we view it) is an icon of Mary and the baby Jesus. To the right, is an image of Jesus.
