Found in Wadi Al Farasa, this small chamber features two columns surrounded by pilasters. A cistern measuring 4 m wide by 4 m long, covered by vaults, was fed water from a larger upper reservoir. Adjacent to the structure is an open space believed to have functioned as a garden irrigated by the cistern's water. Therefore, it is likely that the Garden Hall was utilized as a residence for the guardian overseeing the water cistern along the pathway to the High Place.
