Forgot the name of this church
but the three windows symbolizes the holy trinity (and heaven). the crucification cross symbolizes Jesus (and his sufferings) the bottom three window: the centre on is Christians i think.. the ones on the right and left are the 2 disciples that betrayed him (if i rmbr the story right).. the guy o the right repented and ascended to heaven.. so he gets a window on top.. the guy on the left did not.. and went to hell.. window bottom
