Indiana Jones and The Great Circle: The Order of Giants DLC opens with a Mediterranean map mural that confounds the unwary. While the whole thing looks pretty straightforward on the surface, its solution involves careful photography, hidden clues, and a secret compartment that’s easy to miss. Are you stuck wondering how to proceed? Then step by step, this guide will unravel the whole map mural puzzle for you.
How to Solve the Mediterranean Map Puzzle?

First, photograph the entire mural to solve the Mediterranean map puzzle in the Order of Giants DLC. The best place to be is behind the desk, facing the wall, which offers you the perfect angle for the shot. Afterward, take the photo of the inscription concerning the holy expeditions so that Indy can jot it down. Then, adjust your camera toward the City of Antioch. This action prompts Indy to notice the indentations scattered across the map.


The next step is a little less obvious. Walk right up to the inscription and wait for Indy to react. When he does, you’ll get the option to interact—knock on the wall, and a hidden compartment will open. Inside are two figurines, one representing a giant and the other a pope. Place the giant in Antiochenum and the pope in Santa Sedes. Once both are slotted into place, a secret door will unlock, granting you entry to the Pope’s chambers and pushing the investigation forward.
The connection is clearer for the giant, since Antiochenum is directly mentioned. The pope’s placement at Santa Sedes ties back to the Holy See, though the game doesn’t spell it out as plainly.
