The central point of Mary Queen of the World and St. James the Greater Cathedral-Basilica in Downtown Montreal.
The Latin text inside the cupola reads (translated): You are Peter, and upon this rock I will build my Church. And the gates of hell shall not prevail against it. And I will give to you the keys of the Kingdom of Heaven.
I pretty much laid down on the floor to get this shot. I got many strange looks from the other people in the building.
