For this trophy, you have to climb to the highest point of the city. To reach this point, you have to climb up on a large crane. This crane can be found north-east of your starting position (where the brother is).
In addition to the crane is a building that is flanked by a scaffold. That scaffolding hanging striking blue tarpaulins.
You must now do nothing more than climbing the very long ladder and pick up the trophy. The crane or the bird's eye view is one of eight monuments and is also used for the Bronze award for tourist use.
