You're standing in the dust of the Castel Sant'Angelo. The air smells like old stone and secrets. If you've been playing Indiana Jones and the Great Circle, you know exactly the moment things get real. It's the Basilica puzzle Indiana Jones fans have been obsessing over since the game dropped. Honestly, it’s one of those "stop and scratch your head for twenty minutes" moments that MachineGames is known for. It isn't just about pulling levers; it’s about feeling like Indy, using that journal, and actually paying attention to the environment instead of just looking for a glowing button.
Most people get stuck here because they try to brute-force it. Don't do that. You'll just get frustrated and probably end up whipping a wall out of spite.
What’s Actually Happening in the Basilica?
The setup is classic Indy. You're deep within the heart of the Castel Sant'Angelo in Rome. The goal? You need to align the light and the symbols to reveal the path forward. It sounds simple. It rarely is. The Basilica puzzle Indiana Jones encounters here is a multi-stage logic problem involving mirrors, gold plates, and a very specific sequence that involves the "Great Circle" iconography.
Basically, you’ve got these massive golden discs. They aren't just for show. They reflect light, but they only reflect it if they are positioned at the exact right angle to catch the beam coming from the high windows. The game does a pretty good job of hinting at this through Indy’s dialogue, but if you’re playing with the UI turned down—which is the best way to play, let’s be real—it can be a bit opaque.
The Journal is Your Best Friend
Seriously. Open the journal. It isn't just a menu. In The Great Circle, the journal is a living document that records the sketches and notes Indy makes as you explore. For the Basilica section, the sketches of the Apostles and the specific Roman numerals are the key. If you're ignoring the sketches, you're playing on hard mode for no reason.

The puzzle relies on the relationship between the light beams and the symbols of the four Evangelists: Matthew, Mark, Luke, and John. Each is represented by a specific animal or figure—the Man, the Lion, the Ox, and the Eagle. You’ve seen these in churches before, probably. Here, they are the gears of a massive, ancient machine.
How to Align the Light Beams
First things first. You need to get to the elevated platforms.
The light enters from the top. Your first move is usually to find the primary mirror. This mirror is covered in grime. Give it a wipe. Once the light hits the first gold plate, you’ll see it bounce toward the floor. This is where most players start spinning the pedestals randomly. Stop. Look at the floor. There are faint grooves—tracks, basically—that show where the light wants to go.
- Step One: Rotate the central hub until the beam hits the Lion (Mark).
- Step Two: You'll hear a heavy thunk. That’s the sound of success.
- Step Three: Move to the second level. You'll need to use the whip here to swing across a gap that looks a lot more stable than it actually is.
The trickiest part of the Basilica puzzle Indiana Jones has to solve is the secondary refraction. You have to align two beams at once to hit the central seal. If one is off by even a fraction, the door stays shut. It's kinda finicky. You might think you have it, but check the edges of the light. If it’s "bleeding" off the gold plate, it won’t trigger the mechanism.

Common Mistakes at Castel Sant'Angelo
One thing people consistently miss is the weight-sensitive plate. It isn't enough to just shine the light; sometimes you (or a specific object) need to be standing on the pressure trigger to keep the mirror shutters open. If you step off and the light disappears, you've found your problem. Use one of the nearby stone busts. They aren't just set dressing; they are your "player two" for this puzzle.
Also, watch out for the patrols. Depending on your difficulty settings, Nazis might stumble into the Basilica while you’re mid-puzzle. There is nothing worse than being three inches away from the perfect light alignment only to take a Mauser round to the shoulder. Stealth is your friend here. Clean out the room before you start playing with the mirrors. It makes life easier.
The Symbols and the Great Circle Connection
Why is this puzzle here? From a lore perspective, it’s one of the primary "gates" left by the ancient civilization that understood the Great Circle—the alignment of holy sites around the world. The Basilica puzzle Indiana Jones solves isn't just a lock; it’s a map. When the light finally hits the center of the floor, it doesn't just open a door. It projects a map of the globe onto the stone.
This is where the game’s narrative really starts to pick up speed. You aren't just looking for a golden idol; you're looking for the connection between Rome, Giza, and the other sites. The Basilica is the "anchor" for the European leg of the journey.

Technical Tips for Smooth Puzzling
Sometimes the physics in The Great Circle can be a little... let's say "enthusiastic." If a mirror won't rotate, check if there's a piece of debris wedged in the base. It happens more often than you'd think.
- Gamma Settings: If your screen is too dark, you won't see the etched lines on the floor. Crank the brightness just for this section if you have to.
- Whip Targeting: Use the focus mode (L2/LT) to make sure you're grabbing the right lever. In the heat of the moment, it’s easy to grab a random ring on the wall instead of the puzzle trigger.
- Audio Cues: Listen for the "click." The game uses 3D audio to tell you when a mirror has locked into the correct position. If you have headphones, use them.
Beyond the Basilica
Once you’ve cracked the Basilica puzzle Indiana Jones moves on to the deeper catacombs. But the logic you learned here—light, symbols, and environmental storytelling—remains the core of the game’s challenge. It's a throwback to the old-school adventure games of the 90s, just with 2026 graphics and way better sound design.
The real beauty of this puzzle is that it doesn't treat you like a dummy. It expects you to know a little bit about history, or at least be willing to read Indy's notes to learn it. It’s satisfying. When that final beam of light hits and the floor starts to descend, you actually feel like you earned it.
Actionable Next Steps for Success
To wrap this up and get you back into the game, here is exactly what you should do if you’re currently staring at those mirrors:
- Clear the room: Ensure all enemies are dealt with so you can work in peace.
- Check the Journal: Look at the specific sketch of the "Four Faces." It tells you the order: Man, Lion, Ox, Eagle.
- Wipe the mirrors: Use the interact prompt to clean the dust off any dull surfaces.
- Align the first beam: Start with the light source coming from the ceiling and follow it step-by-step. Don't skip ahead.
- Use the weights: If a beam won't stay put, look for a stone bust to place on the floor switches.
- Listen for the lock: Stop rotating the moment you hear the mechanical "clunk" and see the haptic feedback on your controller.
Once the map is revealed, take a screenshot. It contains hints for the next two locations that aren't immediately added to your objective marker. Good luck, Indy. Try not to get stepped on by a statue.
