Even the house of God can be a house of some mystery.
As you explore the Apostolic Palace in Indiana Jones and the Great Circle, you’ll come across a marble replica of the Great Basilica of Rome with the text on it. Reading the records will activate the mysteries of the House of God. Rebuilding the cathedral will hide its secrets if you know how to get them.

In front of the marble amusement park You will find a lever that sticks out and can be moved left or right. In the beginning Move it all the way to the left. This will cause a secret panel to open on the left side of the cathedral.
Inside the panel was a medal. So grab it and move the lever in front all the way to the right. This will cause another secret door to the right to open. You will find the same slot for storing coins there. So put it there.
Go back to the left and you’ll see another secret compartment open. And this hole holds a golden cup. Pick up the chalice and place it in the “courtyard” of the cathedral. Doing so will open a secret compartment in the front and conceal the mysteries of the House of God.
