The Bulls of Blood: How to find the secret passageway near the fireplace in Angel Courtyard in Indiana Jones and the Great Circle

Make your way through Castel Sant’Angelo until you reach Angel Courtyard, the section where you first learn to lean. Carefully avoid the guard and his dog patrolling the courtyard, then enter the building on the right.

Deal with the fascist and pick up Russo’s Note on the table. While not required to solve the Mystery, you should also collect the Punch Out I Adventure Book nearby. This unlocks the Ability to restore Indy’s stamina after knocking out an enemy, which is incredibly useful.

With Russo’s Note collected, The Bulls of Blood Mystery has officially begun. To continue, walk through the building and past the benches into another room with a fireplace. Knock out the enemy, then pick up the notes on the desk: Red Bulls Card and Angel Courtyard Map.

In the same room, there are two identical paintings of bulls and a totally inconspicuous mural between them. I bet can see where this is going. Approach both bull paintings and rotate them so that both brown bulls face each other, as shown in the screenshot above.

Once you’ve completely rotated both bull paintings, the passage between them will open. Enter the hidden room and pick up Cesare Borgia’s Letter from the box in front of you to complete The Bulls of Blood Mystery!

The Bulls of Blood Mystery Rewards

Further inside the secret room is a lever; pull it to enter a new room with a chest containing cash. From here, you can pull a second lever to unlock the gate and continue the level, skipping past the guard and his dog.

Collecting all the notes and completing The Bulls of Blood rewards you 100 Adventure Points. These Adventure Points are used to learn new Abilities from the Adventure Books found throughout Indiana Jones and the Great Circle — like the Punch Out I book you found earlier.

Indiana Jones and the Great Circle is available for Xbox Series X/S and PC and will launch on PlayStation 5 in 2025.
