From the center of the court where you stood to view the mosque, turn right, towards the main gate flanked by Ramesses II's seated colossi at the back of the court. Pass through that gate and you will access the colonnade. Look for the double statues of Amun and Mut just right and left past the entrance, and the reliefs of the Opet along the two walls behind the columns, starting from the West wall on your right-hand side.
