This is the Paul VI audience hall. It was built in 1971. This is obviously made to resemble a snake, complete with fangs. It is not Christian. But it should be noted that this building is a product of the post Vatican II church. The Vatican II church has a habit of creating buildings and works of "art" that are not Christian, and of destroying older churches that contain more traditional statues, paintings and other sacred relics.
The architect of this monstronsity was most probably a freemason. His name was Pier Luigi Nervi. He made another "church" that looks like an eye in a triangle:

In short, these buildings are NOT Catholic, but represent a freemasonic usurpation within the Church. That is why we see more and more bishops support fag rights and other NWO agendas.
