If you can't find it, there is a landmark icon signifying its location on the map. What I did for this trophy was climb the scaffolding south-east of the Hagia Sofia right next to a doctor and flower bush. I found this to be the fastest way to get to the top and I got it on my first go. Remember to also make full use of the hook-blade so you can shave a few seconds off your climb.
