Hagia Sophia is the 204th card. It is in Card Pack 3.


"The Hagia Sophia is one of the most famous monuments in Istanbul, Turkey. This stunning building has served as a church, a mosque, and is now being used as a museum. In the 16th century, the Janus became a powerful force in the region. There are rumors that a Janus agent, enchanted by the Hagia Sophia's beauty, hid something inside. However, no one has ever been able to confirm this theory. The Janus might be the artistic branch of the Cahill Family, but that doesn't stop them from doing whatever is necessary to protect their secrets. Collect all the cards in this combination to unlock a Clue."


This card, combined with Card 159 and Card 194, forms the Clue Sulfur.
