Best Pantheon is here
Because Rome is such an amazing historical city, with a wonder around every corner, and look! the Pantheon! Very nostalgic structure, since its in london, berlin, paris and others! The door on this one is massive, pure steel! Takes dozens of people to open and shut them. During roman times, it housed pagan gods of Zues and Neptune, Apollo, but today has precious Christian relics.
Notice the obelisque centering the fountain in the square. It came directly from Temple of Karnac in Egypt, as a gift from the Egyptians. awww. how nice!
