As someone from Istanbul, I have always heard stories and legends about the olden Roman city, when it was Constantinople. I am curious about the one I really like, whether it has any truth in it, or is it a just a legend? It goes like this;
"Since Constantinople was build in later years as the new Eastern capital, Romans gave all their best efforts in building and designing the perfect city. The Queen of Cities was so perfect that even in the 15th century, Spanish conquistadors carried the detailed plans of it, so in the New World, they too, can use this perfection as the layouts for the cities they plan to found."
This story is especially used as a sad comparison with modern Istanbul's terrible city planning, saying Turks ruined the perfection.
