Navigating the treacherous corridors of the Vatican requires more than just a whip and a fedora; it requires a keen eye for detail and the patience of a scholar. In Indiana Jones and the Great Circle, the Vatican hub is filled with environmental puzzles that guard valuable upgrades and collectibles. Finding every Indiana Jones and the Great Circle vatican safe code is essential for players looking to maximize Indy's combat prowess and complete their artifact collection in 2026. This guide provides the exact solutions for all seven safes, ranging from the early Belvedere Court discovery to the complex planetary puzzles hidden within the Sistine Chapel's back offices.
Whether you are struggling with the planetary alignment chart or trying to decipher a cryptic poem near the Borgia Tower, we have broken down every step. Each safe involves a unique logic, often tied to "Fieldwork" missions or specific "Mysteries" that unlock as you progress through the narrative. By following this walkthrough, you will ensure no treasure is left behind in the Holy City.
Initial Vatican Safes and Belvedere Court
The first safe you will encounter is located near the very beginning of your journey into the open-world Vatican area. As you step into the Belvedere Court, the atmosphere is tense with enemy patrols, but the rewards tucked away in the first military tent are well worth the risk of detection. This safe serves as an introduction to how the game hides codes on physical objects within the environment.
Video Highlights:
- Location of the Belvedere Court tent safe.
- How to inspect the Ticket Stub for the 5238 code.
- Solving the "Secret of Secrets" planetary puzzle.
- Navigating the Museum Basement for the 7171 code.
Inside the first tent directly in front of you upon entering the court, you will find a desk. Looting this desk reveals a Ticket Stub. By using the game's inspection mechanic, you can see the numbers 3 and 8 on the front. Flipping the ticket over reveals 5 and 2. When combined correctly, this provides the code to unlock the safe sitting right next to the desk.
| Safe Location | Code | Primary Reward | Clue Item |
|---|---|---|---|
| Belvedere Court Tent | 5238 | Combat Skill Book / Money | Ticket Stub |
| Sistine Chapel Office | 4471 | Mystery Completion / Skill Book | Planetary Chart |
| Museum Garden Tent | 6380 | Medicine Locations Book | Calendar & Dice |
Always use Indy's ability to rotate items in the inspection menu. Many codes in the Vatican are split between the front and back of notes or documents.
The Secret of Secrets: Sistine Chapel Puzzle
As you delve deeper into the Vatican, you will eventually gain access to the back offices of the Sistine Chapel. This area houses one of the more complex puzzles in the game, tied to the "Secret of Secrets" mystery. To unlock this safe, you cannot simply find a number written on a wall; you must engage with the history of the saints and the stars.
On the table in the back office, you will find a note instructing you to inspect the statues of Peter with the Key and Paul with the Sword. These figures aren't just for decoration. Picking them up and turning them over reveals astronomical symbols representing specific planets. Once you have these symbols, you must locate the planetary chart in the same room.
Inspect the Statues
Find Peter and Paul on the side tables. Rotate them to find the planetary symbols etched into their bases.
Consult the Planetary Chart
Locate the large chart on the wall. Align the symbols you found with the numbers corresponding to their distance from the Sun.
Input the Code
The resulting calculation leads to the code 4471. Input this into the office safe to claim your prize.
The planetary chart logic relies on the order of planets from the Sun. If you are unfamiliar with basic astronomy, double-check the chart's legend in the room.
Fieldwork Safes: Savage Discovery and A Nun in Trouble
Several safes are locked behind specific Fieldwork missions that trigger as you explore the Vatican. "A Savage Discovery" and "A Nun in Trouble" are two primary side activities that lead Indy to high-security areas containing locked chests and safes. These missions often require finding specific keys before you can even attempt to crack the safe codes.
In "A Savage Discovery," you are tasked with investigating an excavation site. After neutralizing the guards and obtaining the Cellar Key, you can enter the basement beneath the post office near the Tower of Nicholas. Inside, a guard carries a note mentioning "November last year." Given the game's setting in 1937, "last year" refers to 1936, and November is the 11th month.
Savage Discovery Safe
- Location: Cellar under the Post Office
- Code: 1136
- Logic: Date-based (Nov 1936)
- Requirement: Cellar Key from guard
A Nun in Trouble Safe
- Location: Museum Garden Tent
- Code: 6380
- Logic: Calendar and Dice puzzle
- Requirement: Secret Delivery Letter
For the "A Nun in Trouble" safe in the Museum Garden, the solution is much more abstract. You must find the Secret Delivery Letter, which notes a package arrival on October 15th. Cross-referencing this with the in-game calendar reveals the day was a Friday. Looking at the "Dice" code on that specific calendar day yields the final combination.
| Mission Name | Safe Location | Code | Key Logic |
|---|---|---|---|
| Savage Discovery | Post Office Cellar | 1136 | Month/Year Reference |
| A Nun in Trouble | Museum Garden | 6380 | Calendar/Dice Correlation |
| A Nun in Trouble | Museum Basement | 7171 | Hidden Ink/Light Trick |
The Museum Basement safe (7171) is easily missed. After completing the fieldwork, return to the basement and turn off the desk lamp. The code is written in reactive ink that only glows in the dark.
The Father and Son Mystery: Borgia Tower
The "Father and Son" mystery is one of the final puzzles you will solve in the Vatican district. It becomes available only after you have successfully completed the "A Nun in Trouble" mission and received Juliana's Key. This key opens a side room near the Borgia Tower, where Indy finds a room occupied by a cat, a dog, and a very cryptic poem.
To solve this, you must loot the poem and look for circled letters: I, R, I, A, T, A, S, O. These letters must then be applied to a square diagram found in the room. Each letter or combination of letters corresponds to a specific numerical value based on its position in the grid.
| Letter Sequence | Grid Result | Final Code |
|---|---|---|
| I R | 5 | 5 |
| I A | 8 | 8 |
| T A | 7 | 7 |
| S O | 3 | 3 |
Correctly entering 5873 will open the Borgia Tower safe, rewarding you with high-tier loot and completing the Father and Son mystery log.
This safe is particularly rewarding because it represents the culmination of several interlocking side quests. The square diagram logic is a recurring theme in the game's later stages, so mastering it here will help you in Giza and beyond.
Final Vatican Secrets: Signs of Trouble
The last safe in the Vatican region is tied to "Gina's Request," a mystery note found in the Sistine Chapel after finishing the main fieldwork missions. This note triggers the "Signs of Trouble" mystery, leading Indy back to the excavation site. This area is heavily guarded by soldiers, so a stealthy approach is recommended to reach the singular building at the center of the site.
Unlike the previous puzzles, the code for this safe is actually hidden in plain sight if you read the documentation carefully. At the very bottom of the "Gina's Request" note, the year 1891 is mentioned in a context that suggests it serves as a secondary security measure.

Vatican Safe Code FAQ
Q: What is the most important Indiana Jones and the Great Circle vatican safe code to get early?
The code 5238 in the Belvedere Court is the most important early-game safe. It contains a Combat Skill Book that provides essential upgrades for the stealth and combat encounters that follow immediately after.
Q: I can't find the statues for the 4471 code, where are they?
The statues of St. Peter and St. Paul are located on the small side tables within the Sistine Chapel's back office. You must physically pick them up and rotate them to see the planetary symbols on their bases.
Q: Why isn't the code 7171 working in the Museum Basement?
Make sure you have completed the 'A Nun in Trouble' fieldwork first. If the safe is there but you can't see the code, you must interact with the desk lamp to turn it off; the code is only visible in the dark.
Q: Are there any missable safes in the Vatican area?
Most safes can be revisited via fast travel to the 'Garden' or 'Belvedere' locations even after the main story moves on, provided you have the necessary keys like Juliana's Key.
