How to Start House of God
To begin the House of God mystery in Indiana Jones and the Great Circle, pick up the Cleaning Note mystery note, which can be found in front of a Basilica replica on the southeastern side of the Belvedere Courtyard in the Apostolic Palace.
From the Professor, head east and climb up. You’ll then need to drop down over the wall and climb through the window to find this note.

Grab it then interact with the knob and move it all the way to the left. Afterward, let go and head to the right side. Place the Relief Medallion into the slot.
Return to the knob and move it all the way to the right. Head back to the left side to find a second compartment open.
Loot the Golden Chalice and place it in front of the Basilica replica on the platform above the knob to open a hidden compartment in the front.
