There is a Tyger Camera guarding the place. It is behind a chain fence with a weak wall on the right.

You will find it in a passageway at the northern part of the Park Row.

You will find four riddler marks, destroy them with explosive gel.

Go on top of the northern roof edge of the large building east of Solomon Wayne Courthouse.

The question mark is on the chimney on top of the roof.

It is southeast from the previous trophy.

It will open a gate, activate it and then glide down into the area with Wooden Panel.

You will need to destroy the wooden panel with explosive gel after you have activated the pressure pad on the highest rooftop that is east of Solomon Wayne Courthouse.

From there, glide to the wall on the opposite side and then finally to the pad on the ground close to the Riddler trophy. From northern rooftop over the riddler trophy, glide your way to the southern wall and press pressure pad.

For this trophy you need to press pressure pads in the area.

Use explosive gel on the three hidden and Batarang on the fourth mark that is close to the cage with trophy inside. Now comes the interesting part, you have four seconds to destroy them. Use your environment analysis and detective mode to find all the four Riddler question marks.

Go northwest from the Solomon Wayne Courthouse.

It’s on the roof of this building with timed panel just a few steps to the west.

Open your map and look for the building with Park Row written over it.

It is behind the ventilation system and you will have to use remote controlled Batarang to destroy the mark.

Look on the building north of ACE Chemicals.

Wait for the right side Riddler mark to light up and then destroy it using Batarang to get the trophy.

There is a roof near a wall with five Riddler question marks east of where you found the first trophy.

Climb on it and then drop down to the hidden area below to get the trophy.

Go east of ACE chemicals and you will find a gargoyle sprayed with Riddler question mark.
