What is that?

On the side of the building, sticking out, is a little sanctuary or private chapel off of a bedroom. It sticks out the side of the building. Their is a little crucifix in there along with candles, etc. It is believed that no one can live higher than God, so therefore this little sanctuary of God sticks out from the side so no one can physcally live over the top of it, thus no man living higher than God. Next to it you see a dragon, which is a water spout directing the rains and melted snow away from the foundation of the building.
