He continued exploring the area and discovered many of the features reported by Diodorus. Finally, a room was unearthed with three large, strange holes in the floor. Koldewey concluded this had been the location of the chain pumps that raised the water to the garden's roof.
While Koldewey was convinced he'd found the gardens, some modern archaeologists call his discovery into question, arguing that this location is too far from the river to have been irrigated with the amount of water that would have been required. Also, tablets recently found at the site suggest that the location was used for administrative and storage purposes, not as a pleasure garden.
