Yes, upon Peter and the apostles. All the apostles. Peter was chief among them, true, but he is not the only one. Look further. Most of the apostles were murdered for their missionary work. St. Paul was beheaded. There are too many martyrs to count. But Rome is not the center of the faith. It moved to Constantinople, and then all over the world. The Church is universal, or catholic. So, there is not one place better than all others. There are many holy places, like Mt Athos in Greece. There is the Holy Land.

God designs reality using hierarchy.
"Rock" wasn't a name for people in the desert.
Jesus renamed Simon Bar Jonah to Peter which means ROCK and he said UPON THIS ROCK I WILL BUILD MY CHURCH.
It's not that hard, fella.
