Assassin’s Creed Mirage Great Mosque Lost Book Location Guide

The Great Mosque Lost Book is a collectible in Assassin’s Creed Mirage, found in the Quadrangle of the Persians district of the Harbiyah region. When you reach the location of the Lost Book near the Great Mosque, you’ll notice that both entrance doors are barred from the inside.

Fortunately, I’ve discovered a quick way to unlock the door to get the Lost Book as well as a Historical Site collectible.

Where To Find the Great Mosque Lost Book in AC Mirage

The Lost Book can be found in the Quadrangle of the Persians district in the Harbiyah region. It is situated in the same building as one of the thirteen Historical Sites (Kalila and Dimna), just southwest of the Great Mosque.

Now, let’s see how we can get inside the building and grab both collectibles.

How To Get the Lost Book Near Great Mosque

To access the building, make your way to the southwestern side. The door entrance is barred from the inside, but you can enter through an open window above near the small tree in the corner. Simply climb up the wall to reach it.

Once inside the room, go down the stairs and look through the metal bars. You will see a bright red pot that contains explosives on the left side of the room. Use a Throwing Knife to break the pot and initiate an explosion that will open the locked door.

Head back outside, go through the freshly opened door, and grab the Great Mosque Lost Book on the left called Kalila wa-Dimna, as well as the Historical Site on the right known as Kalila and Dimna.
