If you are stumped by the House of God Basilica Puzzle, you will find everything you need to complete it in this Indiana Jones and the Great Circle guide.
Where to Find the House of God Basilica Puzzle

The Basilica Puzzle that begins the House of God quest can be found in the Vatican, the second area you explore in Indiana Jones and the Great Circle. Once you find your way to the Vatican, head to the Apostolic Palace at the bottom right portion of the map and make your way to the upper floors.
The House of God Basilica Puzzle can be found in the long hallway that has an open window leading out to the Excavation Site. Pick up the letter sitting on top of the elaborate cabinet to begin the House of God quest.
How to Solve the House of God Basilica Puzzle

The House of God Basilica Puzzle is a large, ornate puzzle box with several moving parts. These parts have to be tampered with in the right order to access hidden compartments in the cabinet. To begin, interact with the lever on the front of the Basilica Puzzle and move it all the way to the right.

This will open a small compartment on the left side of the cabinet containing a Relief Medallion.

Take the Relief Medallion and interact with the lever again, this time moving it all the way to the left.

This will open another compartment on the right side of the Basilica Puzzle. Take your Relief Medallion and place it in the empty slot in the hidden compartment.

Placing the Relief Medallion in its rightful place will open a third secret compartment on the left side of the Basilica Puzzle. This one was hiding a goblet.

Take the Goblet and place it on top of the Basilica Puzzle to open a final compartment. This one is on the front of the cabinet and contains your reward for completing the puzzle and finishing the House of God quest.

What Do You Get For Solving the House of God Basilica Puzzle?
Your reward for solving the House of God Basilica Puzzle is a map that will guide you to every Ancient Relic in the Vatican. This is extremely handy for anyone looking to solve the Riddles of the Ancients quest.
Ancient Relics are small, cylinder-shaped, white objects that are hidden around almost every location in Indiana Jones and the Great Circle. The Vatican, Gizeh, and Sukhothai all have a stash of Ancient Relics hidden away in secretive corners of the map.

Finding all of them not only completes the Riddles of the Ancients quests in each location but also unlocks a secret ending in the game, so taking the time to find all of these strange Relics is well worth the time and effort it will take you.
There are a lot of Ancient Relics to find, and they are spectacularly well-hidden. However, the task becomes much easier when you locate the Relic Map in each region. So, while these maps are also well-hidden, seeking them out first will make the process much easier.
