Navigating the treacherous corridors of the castle in the Resident Evil 4 remake presents players with several complex environmental challenges. Among these hurdles, the Treasury room obstacle stands out as a memorable test of narrative deduction and careful observation. Overcoming this puzzle is essential for advancing Leon S. Kennedy's high-stakes mission and unlocking the heavy gates that block your primary path forward.

Finding the Treasury and Gathering the Blades

This particular puzzle is encountered during Chapter 7 as you explore the opulent castle structure. Upon entering the Treasury room, you will instantly notice a large locked gate decorated with distinct empty slots designed to hold weapons. To begin solving the riddle, players must first approach the initial three items already placed in the relief carvings.

You will need to interact with the wall to collect the Iron Sword, the Golden Sword, and the Rusted Sword from their respective slots. However, you will quickly notice that a fourth slot remains entirely empty, preventing you from arranging the sequence correctly. The final piece of the puzzle requires you to look toward a nearby metallic gate situated in the same room.

Solving the Gate Mechanism for the Final Piece

To acquire the final weapon, players must look closely at the symbols engraved on the locked gate blocking the side area. You must pull the cord near the gate to activate the animal symbols, which correspond to a deer, a eagle, and a snake. Shooting the matching round emblems scattered along the walls will instantly cause the iron gate to swing open.

Stepping inside this newly opened alcove allows you to approach a small altar holding the missing piece of the set. Here, you will find the Blood-Soaked Sword waiting to be added to your inventory for the main trial. Collecting this final blade gives you the complete collection needed to satisfy the requirements of the central mural fresco.

Correct Placement Order for the Treasury Door

Returning to the main wall relief, you must arrange the four distinct weapons to match the chronological story depicted in the carvings. The narrative flows from left to right, showcasing a young knight's journey from his early training to his eventual demise. Carefully matching the condition of each weapon to the artistic theme of the scene ensures absolute success.

The correct arrangement requires you to place the Iron Sword in the first slot representing the standing knight. The second slot, which depicts the knight receiving an official honor, requires the placement of the Golden Sword. Moving to the third position, you must insert the Blood-Soaked Sword into the battle scene to mirror the violent conflict.

Unlocking the Path and Claiming Your Rewards

The final slot on the far right represents the old age or grave of the warrior, which beautifully matches the appearance of the Rusted Sword. Once all four objects are securely slotted into their correct positions, the massive gate will automatically slide open. This unlocks the primary pathway forward, allowing you to continue navigating the deep castle interior without further delays.

While the primary reward is opening the door to progress the main campaign, the alcove also holds additional hidden resources. Players can search the desks and containers inside the room to secure vital medical items and extra ammunition for upcoming boss fights. Managing these puzzles successfully ensures that you maintain a steady advantage against the growing zealot forces throughout the chapter.
