The hall was built by the Ptolemies. Scenes on the walls show the king emerging from the temple, breaking the earth for the foundation, and placing the first stone. He then dedicates the foundation deposit bricks to Hathor. The hall is surrounded by six rooms. The treasury room contained holy objects made of metal. The Nile room provided an exit for the priests to go out and bring in water. A smaller room was for the convenience of the priests. This room allowed them to move between rooms easier. Another room was for the priests to make and store incense and perfumes. Room number five was for storage and room number six had an outside exit. This room was for bringing in food and drink for festivals.
