A pointed cone shape on top of a building is called a spire, especially when it rises from the roof of a church pointing sharply up toward the sky. Many church spires have a cross at the very top.
Crucifix. A cross with a representation of Jesus' body hanging from it. It is primarily used in Catholic, Anglican, Lutheran, and Eastern Orthodox churches (where the figure is painted), and it emphasizes Christ's sacrifice—his death by crucifixion.
