The Pantheum. This building was built by the ancient romans in an attempt to please all gods. This was a place wheere one could pray to every god. Later, when Christianity became popular, it was re-furbished and turned into a Church. You'll notice that the triangle above the columns seems a little bare. That's because it is. The christians of the time decided that the pagan representations shown on the facade of the building had to go. I wonder how they made those decisions, because there are plenty of other pagan representations everywhere else, including Vatican City and street monuments.
