Trip Review- The Hagia Sophia details

The Hagia Sophia is a building that emits the ancient world.  As you look up as you walk around and try to take it in, it could be 1000 years earlier.  It is sad how the great empires collapse.  The treasures, relics and gold all vanish.  I can't imagine how much of the ancient world was on view around 520 AD.  Many of the great ancient works were in Constantinople.  It would have been by far the greatest collection ever assembled.
