Istanbul Day 2 - this was a jammed pack day.  We started the morning by visiting the Hippodrome, which once held chariot races for spectators up to 100,000 people.  Now, it’s an open area where a lot of people congregate and relax.  The Hippodrome is just west of the Blue Mosque and from the west entrance, you get to see the Blue Mosque in its symmetrical form.  It’s quite impressive to see from the outside and the interior is very beautiful with hand painted tiles and walls everywhere.  The mosque was completed in 1616 by Sultan Ahmed I and is still a working mosque.  The main dome is huge and the ceiling is dominated by blue colors and hence the name.
