Like most churches of this period, the Odzun church does not have windows at waist level. Its four windows are narrow slats high up near the dome and let in light only just before sunset or after sunrise. On either side of a sunrise-facing window stand sculpted angels holding snakes. The two snakes entwine to decorate a bust of Christ. This is very unusual in Christian art. In Christian art the snake represents evil, and is never found in the same space as Christ.
