This guide details how to find and unlock the safe in the Museum Wing Storage Room within the Vatican City section of Indiana Jones and the Dial of Destiny.
Locating the Museum Wing Storage Room Safe
The Museum Wing Storage Room is situated between the Belvedere Courtyard and the Pharmacy in Vatican City. Proceed to the right from the Belvedere Courtyard; you'll find a gate leading into the Museum Wing courtyard. Follow the courtyard path until you reach an open door at its end. This door leads directly into the storage room containing the locked safe.

Unlocking the Safe
Unlike many safes in the game which require finding a code on a note, this safe's code is cleverly concealed. In the storage room, locate a green lamp positioned on a crate to the left. Switch off the lamp. This action reveals the safe combination, written in pink, on the wooden crates beneath the lamp.

The code is 7171. Enter this code into the safe to unlock it.
Inside, you'll find the Drinking Horn artifact, a valuable addition to your Lost Artifacts of Europe collection.
This completes the guide to finding and unlocking the safe in the Museum Wing Storage Room.
