Today was a day to tour the Old City of Istanbul.  It was an opportunity to see many sultan palaces and one of the oldest working water cysterns in the world.  We also made a quick visit to what has to be the world'f first and oldest mall, the Grand Bazaar.  It is said if you are in need of anything you can find it there.   The day ended with a traditinal Turkish dinner on a river boat on the Golden Horn, which leads into the Black Sea.
