There is an area called "colonnaded street", or rather what's left of it. Some may say it is an utter mess, others may hold it is a romantic spot full of surprises. Most people avoid it, but in 2013 I spent quite some time risking sprained ankles to at least give some impression. I suppose some day it will be restored and look just like the colonnaded streets in, say, Perge or Ephesus.
